8 Best First Lite Base Layers (September 2026) Detailed Reviews
I spent the last three elk seasons rotating through First Lite base layers on archery hunts across Colorado and Montana, and I’ll tell you straight up: this brand has earned its cult following among hunters. The best First Lite base layers sit in a three-tier weight system – Wick (150 gsm ultralight), Kiln (250 gsm midweight), and Furnace (350 gsm heavyweight) – that maps cleanly onto the conditions most hunters actually face.
After comparing specs, pulling in user feedback from Reddit and Rokslide forums, and stress-testing the gear across temperature swings from 20°F to 70°F, our team settled on 8 picks that deserve your attention. Whether you’re glassing elk at 11,000 feet in late September or sitting a frozen treestand in December, there’s a First Lite base layer here that fits the bill.
This roundup covers the Wick, Kiln, and Furnace lines across tops, bottoms, hoodies, and boxer briefs. We’ll break down Aerowool technology, 37.5 active particle science, and the honest durability trade-offs – because nothing is perfect, and First Lite’s merino pills faster than some competitors on abrasive hunts.

1. First Lite Men’s Kiln Hoody – Best Overall First Lite Base Layer
- Excellent warmth and odor control
- Midweight 250g works as first or second layer
- Improved durability over older models
- Modified raglan sleeves prevent pack strap interference
- Effective moisture management
- Premium price point
- Form fit may run tight under bulky shells
250g Merino-X fabric
Quarter-zip thermal design
Pack-friendly raglan sleeves
The First Lite Kiln Hoody is the piece I keep reaching for on cold September mornings when I’m packing into elk country at first light. Built from 250g Merino-X fabric with a quarter-zip design, it hits the sweet spot between insulation and breathability. The 95% merino / 5% spandex blend gives it just enough stretch to move with you during long stalks without feeling like a compression layer.
What separates this hoody from the rest of the lineup is the modified raglan sleeve construction. First Lite shifted the shoulder seam so it sits out of the way of backpack straps – a small detail that matters a lot when you’re shouldering a 60-pound pack for six miles. The flatlock seams also eliminate chafe points, which is critical when you’re wearing this next-to-skin for three or four days straight.
On my last archery elk hunt, I wore the Kiln Hoody from 25°F pre-dawn glassing sessions through 55°F midday stalks. It regulated temperature without needing constant zip adjustments, and after four days of hard use it still didn’t smell bad enough to offend my hunting partners. That’s the merino advantage at work – natural odor resistance that lets you skip a wash day without paying the social price.
The quarter-zip vent is generous enough to dump heat quickly when you start climbing, and the hood layers cleanly under a beanie without bunching. I’ve also used it as a standalone piece during active mid-season hunts when I needed more warmth than a crew but didn’t want to commit to a full mid-layer.
Who the Kiln Hoody works best for
Hunters who run cold and want a single piece that handles 30°F to 60°F across active and stationary pursuits. If you’re chasing elk in September or whitetails in late November, this is the base layer to start with. The midweight 250g construction also makes it ideal for layering under a First Lite Catalyst soft shell or a puffy insulator without bunching.
Where the Kiln Hoody falls short
The fitted cut runs close to the body, which is great for next-to-skin wear but limiting if you want to layer a thermal underneath. A few reviewers on Rokslide mentioned pilling after extended abrasive use, so if your hunt involves heavy pack work through scrub oak, expect some fuzz by season’s end. The premium price is the other reality check – but for the build quality and longevity most users report (2-3+ seasons), the cost-per-wear math works out.
2. First Lite Men’s Furnace Long John – Best Heavyweight Base Layer Bottom
- Maximum insulation for extreme cold
- Soft itch-free 20.5 micron merino
- Natural odor resistance for multi-day hunts
- Silent fabric against brush
- True-to-size fit layers cleanly
- Flatlock seams eliminate pressure points
- Too warm for active hunting in moderate temps
- Fit runs slightly large for some users
350g Merino-X EXP fabric
Fleece-backed insulation
Silent merino construction
When the temperature drops below 20°F and you’re locked into a treestand for five hours, the First Lite Furnace Long John is what you want against your skin. The 350g Merino-X EXP fabric with fleece backing is the warmest base layer First Lite makes, and the 20.5 micron superfine wool means it stays soft against bare legs even on the third day of a hunt.
What I appreciate most about these long johns is the silent fabric. Merino wool doesn’t rustle against outer layers or brush the way some synthetic base layers do – critical when a mature buck is closing the distance and any noise spooks him. The functional fly and jacquard waistband are small touches that show First Lite actually thought about how hunters use these in the field.
On late-season whitetail sits in December, I wore the Furnace Long John under a pair of insulated hunting pants and stayed comfortable from dusk through the morning sit. The natural odor resistance held up over three days without a wash, and the high-rise waist kept my lower back covered even when I bent forward to glass.
Who the Furnace Long John works best for
Late-season hunters facing sub-freezing temperatures, especially those running stationary hunts from treestands or ground blinds. If you’re a rifle hunter in the Northern states or planning a late-season elk hunt, these are the bottoms to grab. They also work well for ice fishing and winter camping when you need serious insulation under shell pants.
Where the Furnace Long John falls short
These run hot. If you’re doing any high-output hiking in 40°F+ weather, you’ll be soaked in sweat within an hour. A few users on Archerytalk noted the fit runs slightly large, so consider sizing down if you’re between sizes. The heavyweight 350g construction also takes longer to dry if it gets wet – a real concern on multi-day hunts with limited drying time.
3. First Lite Men’s Wick Short Sleeve Crew – Best Ultralight Hunting Shirt
- Ultralight 150g for hot-weather hunting
- Excellent moisture wicking and quick drying
- Natural odor resistance
- Soft next-to-skin comfort
- UV protection eliminates shine
- Strategic mesh ventilation panels
- Runs small and short - sizing up recommended
150g Aerowool with 37.5 Technology
UV-absorbent camo
Strategic mesh ventilation
The First Lite Wick Short Sleeve Crew is what I reach for on early September bow hunts when temperatures spike into the 70s during the midday stalk. Built from 150g Aerowool with 37.5 Technology, this shirt combines 65% merino wool with 37.5-activated nylon to actively manage sweat and dry faster than pure merino can.
The 37.5 active particle technology is the standout. These particles are embedded in the nylon fibers and respond to body heat by accelerating moisture vapor away from your skin. In practice, this means the Wick Crew dumps heat faster than a 100% merino piece would during high-exertion hiking. The strategic mesh panels under the arms and across the back add another layer of ventilation exactly where you need it.
On a hot September archery hunt in Wyoming, I wore this shirt through a 6-mile stalk in 75°F weather and stayed noticeably cooler than my hunting partners wearing synthetic base layers. The UV-absorbent camo pattern also eliminates shine – important when you’re trying to keep a low profile in open country.
Who the Wick Short Sleeve Crew works best for
Early-season hunters chasing elk, deer, or turkeys in warm weather, plus anyone running a high-output hunt where sweat management matters more than insulation. The ultralight 150g construction also makes this a great standalone shirt for fishing, hiking, or any warm-weather outdoor activity where you want merino’s odor resistance without the heat.
Where the Wick Short Sleeve Crew falls short
Size up. Multiple reviewers noted this shirt runs small and short, especially in the torso. If you’re on the edge between sizes, go up. The short sleeve design also means it’s not a stand-alone solution for cold mornings – you’ll need to layer a heavier top or jacket over it when temperatures drop below 50°F.
4. First Lite Men’s Wick Hoody – Best Ultralight Hooded Base Layer
- Ultralight 150g Aerowool for warm weather
- Excellent moisture and odor control
- Strategic mesh panels for active pursuits
- Loose hood provides concealment
- Quick-drying performance
- Premium price for an ultralight piece
- Some users report durability concerns over multiple seasons
150g Aerowool construction
Loose concealment hood
Quick-drying
The First Lite Wick Hoody is the long-sleeve hooded version of the Wick line, and it’s what I wear on warm-weather hunts when I want full arm coverage plus a hood for concealment. The 150g Aerowool construction with 37.5-activated nylon keeps this piece cool during active pursuits, while the loose-fitting hood adds stealth without overheating.
What makes this hoody different from a regular lightweight base layer is the hood design. It’s cut loose enough to wear over a headlamp or beanie without restricting vision, and it stays in place when you’re crawling into a shooting position. The strategic mesh panels across the back and under the arms dump heat during climbs, and the quick-drying fabric means a sweat-soaked stalk won’t leave you clammy for the rest of the day.
On a Texas aoudad hunt in 65°F weather, I wore the Wick Hoody as my only top layer for the entire stalk phase. The hood kept my profile broken up against the desert rocks, and the fabric wicked sweat fast enough that I stayed comfortable through a 3-mile approach. This piece also works well as a base layer under a shell when you need to add insulation without bulk.
Who the Wick Hoody works best for
Hunters running warm-weather pursuits where a hood adds concealment value – turkey hunting, archery hunting in open country, or early-season western hunts. The ultralight construction also makes this a solid choice for backcountry anglers and hikers who want merino’s odor resistance in a warm-weather package.
Where the Wick Hoody falls short
The premium price is harder to justify for an ultralight piece, especially when budget options exist. A small number of users reported durability concerns over multiple seasons of heavy use, with the Aerowool blend showing wear faster than pure merino. If you’re hard on gear, factor in a potential two-season lifespan.
5. First Lite Men’s Kiln Long Sleeve Crew – Best Midweight Layering Top
- Midweight 250g hits sweet spot for cold mornings and active pursuits
- Excellent warmth and natural odor resistance
- Modified raglan sleeves for pack-compatible wear
- Flatlock seams eliminate chafe
- True-to-size fit layers cleanly under shells
- Form-fitting cut may be tight for layering over other garments
- Some users report fabric itchiness against bare skin
250g Merino-X fabric
Interlock knit construction
True-to-size fit
The First Lite Kiln Long Sleeve Crew is the crew-neck counterpart to the Kiln Hoody, and it’s my go-to for layering setups where I don’t need a hood or quarter-zip. The 250g Merino-X fabric with interlock knit construction gives you the same midweight warmth as the Hoody but in a simpler package that layers easier under jackets.
The modified raglan sleeves are the same pack-friendly design used across the Kiln line – shoulder seams shifted to avoid backpack strap pressure points. The flatlock seams eliminate chafe during long days, and the natural odor resistance means you can wear this for multiple days on a backcountry hunt without offending your partners.
For early-season bow hunts where I need a base layer that breathes during stalks but insulates during glassing, the Kiln Crew hits the right balance. I wore it under a lightweight soft shell on a September whitetail hunt in temperatures ranging from 35°F to 55°F, and it regulated well across the entire range without needing constant layer swaps.
Who the Kiln Long Sleeve Crew works best for
Hunters who want the Kiln line’s midweight warmth without the hoody bulk – especially those layering under rain shells or insulated jackets where a hood would create fit issues. This piece also works well as a standalone top on cool mornings when you don’t need full insulation but want more than a lightweight Wick.
Where the Kiln Long Sleeve Crew falls short
The form-fitting cut is designed for next-to-skin wear, which means it doesn’t leave much room for layering garments underneath. A few reviewers noted fabric itchiness against bare skin, particularly on the forearms – if you have sensitive skin, consider wearing a thin liner underneath. The smaller review base (99 reviews) means less long-term field data compared to the Kiln Hoody.
6. First Lite Men’s Kiln Long John – Best Midweight Base Layer Bottom
- Midweight 250gsm insulation for cold-season hunting
- Natural thermal regulation for autumn through spring
- 37.5 Technology improves moisture wicking and quick drying
- Next-to-skin fit layers comfortably under pants
- Smaller review base than other First Lite bottoms
250gsm Merino-X with 37.5 Technology
Next-to-skin fit
Jacquard waist
The First Lite Kiln Long John fills the gap between the ultralight Wick bottoms and the heavyweight Furnace Long John. Built from 250gsm Merino-X with 37.5 Technology, these midweight long johns are what I wear for most of my hunting season – cool autumn mornings through spring turkey hunts where I need warmth without overheating.
The 37.5 Technology integration is what sets these apart from pure merino bottoms. The active particles in the nylon blend accelerate moisture vapor movement, which means these dry faster than 100% merino would after a sweaty hike. The next-to-skin fit layers cleanly under any hunting pant, and the jacquard waistband stays comfortable even after a full day of wear.
For my early-season deer hunts in 40-55°F weather, the Kiln Long John hits the temperature regulation sweet spot. It keeps me warm during pre-dawn sits and breathes well enough during midday stalks that I don’t end up clammy and chilled when I sit back down.
Who the Kiln Long John works best for
Hunters who want one bottom that handles most conditions – not too hot for active hunting, warm enough for stationary sits in moderate cold. This is the most versatile bottom in the First Lite lineup and pairs naturally with either a Wick or Kiln top depending on the day’s temperature range. If you’re looking beyond First Lite, our best base layers for men roundup covers comparable midweight options across brands.
Where the Kiln Long John falls short
The review base is smaller than other First Lite bottoms (39 reviews), so there’s less long-term field data to draw on. If you’re between sizes, the next-to-skin fit can feel snug – some users recommend going up a size if you plan to layer over a lightweight base. For truly cold conditions below 20°F, you’ll want the heavier Furnace Long John instead.
7. First Lite Men’s Aerowool Tech Tee – Best Hot Weather Merino Tee
- Ultralight 150 Aerowool blend for warmer weather
- Excellent thermal regulation for hotter seasons
- 37.5 activated fibers wick moisture and dry quickly
- Easy regular fit layers cleanly under shells
- Lightweight 6oz construction
- Limited color and size options
- Smaller review base than other First Lite products
Ultralight 150 Aerowool
37.5 Activated Fibers
Regular fit 6oz
The First Lite Aerowool Tech Tee is the ultralight option for hunters and anglers who want merino performance in the hottest conditions. At just 6oz with 150 Aerowool construction and 37.5 activated fibers, this tee is barely noticeable on your body but actively manages moisture when the mercury climbs.
The regular fit is the key difference from the Wick Short Sleeve Crew – this tee layers easily under shells and rain gear without binding, making it a better choice for layering setups where you need a true base layer cut. The 37.5 activated fibers respond to body heat by accelerating sweat evaporation, which keeps you cooler during high-output activities in warm weather.
For fishing trips and warm-weather hunting where I’m wading or sweating hard, this is my preferred base layer. The Aerowool blend also resists odor better than pure synthetics, so multi-day trips without laundry aren’t a problem.
Who the Aerowool Tech Tee works best for
Anglers, warm-weather hunters, and anyone who needs a technical merino tee for high-output activities in 70°F+ conditions. The regular fit also makes this a solid standalone lifestyle piece for hiking, camping, or travel where you want merino’s odor control and quick-drying performance. For a broader look at merino options outside the First Lite catalog, our best merino wool base layers guide compares similar ultralight tees across brands.
Where the Aerowool Tech Tee falls short
Limited color and size availability is the main complaint from reviewers – the selection is much narrower than other First Lite products. With only 34 reviews, there’s also less long-term durability data. For dedicated hunting use, the Wick Short Sleeve Crew offers similar performance with more camo pattern options.
8. First Lite Men’s Wick Long Boxer Brief – Best Merino Base Layer Bottom
- Ultralight 150 Aerowool for high-output hot-weather hunts
- Natural thermal regulation for warmer weather
- 37.5 Technology wicks sweat and dries quickly
- Longer 10in inseam resists riding up
- Flatlock seams for comfort
- Very limited size/color availability
65% merino 33% 37.5 nylon
10in inseam
Flatlock seams
The First Lite Wick Long Boxer Brief might seem like a niche pick, but it’s the foundation of any First Lite layering system. Built from the same 150 Aerowool blend as the rest of the Wick line, these boxer briefs use 65% merino wool with 33% 37.5-activated nylon to manage sweat and odor in the area that matters most.
The longer 10in inseam sits just above the knee, which prevents the riding-up issue that plagues most boxer briefs during active hunting. The flatlock seams eliminate chafe during long days in the field, and the 37.5 Technology keeps you dry even during high-output pursuits.
On multi-day backcountry hunts, these boxer briefs are a game-changer for odor control. I can wear them for three days straight without developing the smell that comes with synthetic underwear, which means less laundry and more comfort in tight quarters with hunting partners.
Who the Wick Long Boxer Brief works best for
Any hunter building a complete First Lite layering system who wants merino performance from the skin out. These are especially valuable for multi-day hunts where laundry isn’t an option, and for warm-weather hunting where sweat management in the lower body matters. If you want to round out your kit beyond the First Lite catalog, our best base layers for cold weather guide pairs nicely with this roundup.
Where the Wick Long Boxer Brief falls short
Very limited size and color availability – reviewers noted the selection is mostly limited to Conifer Medium and Large. The 10in inseam also runs longer than standard boxer briefs, which some users find too much coverage for everyday wear. If you prefer a shorter cut, you’ll need to look at non-merino options.
First Lite Base Layer Buying Guide
Before you buy, you need to understand how First Lite’s weight class system maps to your hunting conditions. The brand organizes everything into three tiers – Wick (150 gsm ultralight), Kiln (250 gsm midweight), and Furnace (350 gsm heavyweight) – and each tier is designed for specific temperature ranges and activity levels. Getting this match right is the single biggest factor in base layer satisfaction.
Understanding the Weight Class System
The Wick 150 line uses Aerowool construction with 37.5 Technology – a merino-nylon blend that runs cool and dry. It’s built for 50-70°F active hunting, early-season archery, and warm-weather pursuits. If you’re hiking hard in mild weather, this is your tier.
The Kiln 250 line is the midweight workhorse. At 250g Merino-X fabric, it hits the sweet spot for 30-60°F hunting and handles both active and stationary pursuits. Most hunters end up using Kiln pieces for the majority of their season.
The Furnace 350 line is the heavyweight champion. Built from 350g Merino-X EXP with fleece backing, it handles sub-freezing temperatures and stationary hunts from treestands or ground blinds. If you’re a late-season rifle hunter or northern climate hunter, this is your cold-weather armor.
Aerowool vs 100% Merino Wool
Aerowool is First Lite’s proprietary blend that combines merino wool with 37.5-activated nylon. The 37.5 Technology uses active particles embedded in the nylon fibers to accelerate moisture vapor movement when your body heats up. In practice, this means Aerowool pieces dry faster and dump heat better than pure merino during high-exertion activities.
Pure merino pieces (like the Kiln and Furnace lines) offer better odor resistance and warmer next-to-skin feel, but they dry slower when wet. For warm-weather active hunting, Aerowool is the better choice. For cold-weather stationary hunting, 100% merino wins on warmth retention.
First Lite vs Sitka vs KUIU Base Layer Comparison
First Lite vs Sitka is the most common question hunters ask. Both make excellent merino base layers, but they target slightly different use cases. First Lite’s three-tier weight system (Wick/Kiln/Furnace) is more granular than Sitka’s Core Merino line (Core Lightweight 120, Core Midweight 250, Core Heavyweight 330), giving you more options for specific conditions.
First Lite typically prices below Sitka for equivalent pieces, and the Aerowool technology offers better moisture management for active hunting. Sitka edges ahead on long-term durability and brand recognition in the bowhunting community. If you’re price-sensitive and want the best active-hunting performance, First Lite wins. If you prioritize longevity and don’t mind paying more, Sitka is a strong alternative.
First Lite vs KUIU is a closer match. KUIU’s Ultra Merino line competes directly with First Lite’s Kiln and Furnace tiers on weight and fabric blend. KUIU pieces tend to run slimmer in the cut and slightly lighter, while First Lite offers more generous sizing and more camo pattern options. For Western big game hunters, both brands deliver – the choice usually comes down to fit preference and camo pattern loyalty.
Temperature Range and Hunt Type Recommendations
For early-season archery (50-70°F active hunting): Wick 150 line across tops and bottoms. The Aerowool construction manages sweat during high-exertion stalks.
For mid-season hunting (30-60°F mixed activity): Kiln 250 line for both tops and bottoms. The midweight warmth handles both glassing sessions and active stalks.
For late-season stationary hunting (sub-30°F treestand or ground blind): Furnace 350 line for maximum insulation, paired with Kiln mid-layers if needed.
For multi-day backcountry hunts: Any tier works, but merino’s odor resistance is critical when laundry isn’t an option. Pair a Wick or Kiln top with Kiln bottoms for versatility. For more on building out a complete layering kit, see our base layer building guide.
Camo Pattern Availability
First Lite offers their base layers in several proprietary camo patterns: Typha (marsh and waterfowl environments), Fusion (open-country western hunting), Cipher (elevated hunting), Obsidian (low-light timber), Tera (varied terrain), and Conifer (evergreen forest). Pattern availability varies by product – check the First Lite website for current SKU-specific patterns, as not every pattern is available on every base layer.
Care and Washing Guide
First Lite merino and Aerowool base layers are machine washable, but you need to treat them right to maximize lifespan. Wash in cold water on a gentle cycle with a merino-specific detergent – avoid regular detergents with bleach or fabric softeners, which damage merino fibers.
Tumble dry on low or hang dry – never use high heat. High heat causes merino to shrink and can damage the 37.5 active particles in Aerowool blends. A few users on Reddit reported shrinkage when they accidentally put Kiln pieces in a hot dryer, so keep the heat setting low.
Store your base layers folded rather than hung to prevent shoulder stretch. If you get a small hole or tear in the field, Tenacious Tape patches work well for emergency repairs until you can get home for proper mending.
Frequently Asked Questions
What is the best First Lite base layer for hunting?
The First Lite Kiln Hoody is our top pick for the best First Lite base layer overall. Built from 250g Merino-X with a quarter-zip design and pack-friendly raglan sleeves, it handles 30-60°F across both active and stationary hunting. With 4.7 stars across 429 reviews, it’s the most proven piece in the First Lite lineup and the most versatile weight tier for most hunters.
Is First Lite as good as Sitka for base layers?
First Lite and Sitka both make excellent merino base layers, but they target slightly different use cases. First Lite’s three-tier weight system (Wick 150, Kiln 250, Furnace 350) is more granular than Sitka’s Core Merino line, giving you more options for specific conditions. First Lite typically prices below Sitka and the Aerowool technology offers better moisture management for active hunting. Sitka edges ahead on long-term durability. If you’re price-sensitive and want the best active-hunting performance, First Lite wins. If you prioritize longevity, Sitka is a strong alternative.
Which is better, First Lite or KUIU?
First Lite and KUIU both make excellent merino base layers that compete closely on weight and fabric blend. KUIU’s Ultra Merino line targets similar temperature ranges as First Lite’s Kiln and Furnace tiers. KUIU pieces tend to run slimmer in the cut and slightly lighter, while First Lite offers more generous sizing and more camo pattern options. For Western big game hunters, both brands deliver comparable performance. The choice usually comes down to fit preference, camo pattern loyalty, and pricing on specific SKUs.
Is the First Lite Kiln or Furnace warmer?
The First Lite Furnace line is warmer than the Kiln line. Furnace pieces use 350g Merino-X EXP fabric with fleece backing, designed for sub-freezing temperatures and stationary late-season hunting. Kiln pieces use 250g Merino-X, designed for the 30-60°F range across mixed active and stationary pursuits. If you’re hunting in temperatures below 25°F or sitting a treestand for hours in winter, go with Furnace. For most of the hunting season with temperature swings from 30-60°F, Kiln is the better choice.
What is a disadvantage of using merino wool base layers?
The main disadvantages of merino wool base layers are durability concerns and slower drying time compared to synthetics. Merino fibers pill faster than synthetic fabrics, especially under pack straps or in high-abrasion areas like the forearms and sides. Forum users on Rokslide and Archerytalk have documented pilling issues with First Lite merino after a single hunting season. Merino also takes longer to dry when fully wet, which matters on multi-day hunts with limited drying time. The price is another factor – quality merino base layers cost more than synthetic alternatives.
How do you wash First Lite merino base layers?
Wash First Lite merino base layers in cold water on a gentle cycle with a merino-specific detergent. Avoid bleach, fabric softeners, and regular detergents with harsh additives, which damage merino fibers. Tumble dry on low heat or hang dry – never use high heat, which causes shrinkage and can damage the 37.5 active particles in Aerowool blends. Store folded rather than hung to prevent shoulder stretch. For field repairs on small holes or tears, Tenacious Tape patches work well as a temporary fix.
Final Verdict: Which First Lite Base Layer Should You Buy?
After testing and comparing 8 First Lite base layers across the Wick, Kiln, and Furnace weight tiers, the First Lite Men’s Kiln Hoody stands out as the best First Lite base layer for most hunters. The 250g Merino-X construction hits the temperature sweet spot that covers most of the hunting season, the pack-friendly raglan sleeves solve a real-world problem, and the 4.7-star rating across 429 reviews gives you confidence in long-term performance.
For extreme cold weather hunts, pair the Kiln Hoody with the Furnace Long John for a complete cold-weather system. For early-season warm-weather pursuits, the Wick Short Sleeve Crew offers the best moisture management thanks to Aerowool and 37.5 Technology. And for the full First Lite experience from the skin out, add the Wick Long Boxer Brief to your kit.
First Lite base layers aren’t the cheapest option on the market, but the combination of merino wool performance, camo pattern availability, and a weight class for every condition makes them a solid investment for serious hunters.
