Sitka's Lightest Base Layer for Early Season Hunts

The Core Merino 120 LS Crew is Sitka's lightest merino base layer, built for early season pursuits when conditions shift fast. The 120-gram, 17.5-micron ArmorSpun merino wool blend regulates temperature through changing activity levels while naturally suppressing your scent. Snag-preventative stitching along the sleeves holds up against pack abrasion, and low-profile integrated thumb holes keep layering clean. This is field-tested insulation that's trail-ready from first light to last mile — easy-care merino you wash and dry with regular laundry, built rugged and season-proven to perform for years to come.

Merino That Survives Pack Straps and Multi-Day Hunts

Merino That Survives Pack Straps and Multi-Day Hunts

Most merino base layers feel good on day one but lack the rugged construction to survive a few rocky pack-ins. The ArmorSpun merino wool in the Core Merino 120 LS Crew wraps each fiber in a protective layer that resists the abrasion pack straps inflict over miles of steep terrain. Snag-preventative stitching along the sleeves adds another layer of defense. At Hunt Premium, we don't list gear we wouldn't bet a $3,000 tag on — and this base layer has earned its spot through season-proven durability where other merino fails.

Temperature Regulation for Early Season Surges

Temperature Regulation for Early Season Surges

Early season hunting means climbing hard in cool mornings, sweating on steep ascents, then cooling fast at glassing points. The 120-gram merino wool blend in this crew regulates temperature naturally — pulling moisture away from your skin during exertion and retaining warmth when you stop moving. At 6.1 oz total weight, it disappears under your mid-layer without adding bulk or restricting your draw. Low-profile integrated thumb holes keep the sleeves seated while you pull on an outer layer at first light, so you are not fighting your base layer when the bull steps out.

Scent Control Without the Chemical Gimmicks

Scent Control Without the Chemical Gimmicks

Merino wool naturally resists odor by inhibiting the bacteria that cause it — no silver treatments, no antimicrobial sprays that wash out after three trips. The 17.5-micron fiber diameter keeps this crew soft against your skin without the itch that heavier wool blends create. And unlike synthetic base layers that hold onto body odor even after washing, the Core Merino 120 is easy-care: wash it and dry it with your regular laundry. This is trail-ready simplicity that performs on a five-day backcountry elk hunt without becoming the shirt everyone at camp can smell.

“Wore this on a seven-day September elk hunt in Colorado. Climbed hard every morning, glassed in the afternoons, and never once felt like I was wearing the wrong base layer. No stink after day three, which I cannot say for any synthetic I have owned. The thumb holes are a small detail that matters when you are layering up at 4:30 AM with cold hands.”

Frequently Asked Questions

Synthetic base layers cost less upfront but hold odor after one hard day afield and lose their moisture-wicking performance as fibers degrade. The Core Merino 120 LS Crew uses natural merino wool that resists odor for days without chemical treatments and regulates temperature more effectively than polyester blends. At 6.1 oz with ArmorSpun durability, this is a base layer that outlasts synthetic alternatives across multiple hunting seasons. The $90 investment covers a base layer that keeps performing when synthetics have already been retired.
Yes. Hunt Premium is an authorized Sitka dealer, which means every Core Merino 120 LS Crew ships with full manufacturer warranty support. Sitka stands behind their products with a warranty that covers defects in materials and workmanship. Buying from an authorized dealer ensures you receive genuine Sitka product — not grey-market inventory with voided warranty coverage. Your $90 purchase is backed by the brand directly, not a third-party seller with no accountability if something goes wrong.
The Core Merino 120 LS Crew is built for early season pursuits — September elk hunts in the Rockies, early archery whitetail in the Midwest, high-desert antelope in Wyoming where mornings start cold but midday temps climb. The 120-gram merino weight handles the temperature swings of active hunting: warm enough for cool morning glassing sessions, breathable enough for steep climbs in the afternoon. Pair it with a heavier Sitka mid-layer when temps drop below freezing, but as a standalone base layer, this is designed for early season when conditions change fast.
Sitka's Core Merino 120 LS Crew is available in Medium through 3XL and follows Sitka's standard athletic fit. It is designed to sit close to the body for effective moisture management and temperature regulation without restricting movement. If you are between sizes or plan to layer a heavy mid-layer over it, going up one size gives you a bit more room without sacrificing performance. The low-profile thumb holes are integrated into the sleeve cuff and work at any size without feeling tight or pulling.
The Core Merino 120 is easy-care merino — wash it and dry it with your regular laundry. No special detergents, no hang-drying required. The ArmorSpun construction gives this merino the durability to handle machine washing without pilling or losing shape the way traditional merino does. Avoid fabric softeners, which coat the fibers and reduce moisture-wicking performance. That is the only real rule. After a five-day backcountry elk hunt, throw it in the wash like everything else and it comes out ready for the next trip.
Yes. Hunt Premium offers a 30-day return window on the Core Merino 120 LS Crew. The item must be unworn, unwashed, and in original packaging with all tags attached. If the sizing is not right for your build or layering system, send it back and we will process the return. Free shipping is included on every order, and returns are straightforward. Try it on at home, and if it does not fit your system, send it back on us.
The ArmorSpun merino wool construction specifically addresses pack abrasion — one of the main failure points for traditional merino base layers. Snag-preventative stitching along the sleeves resists the constant rubbing from hip belt and shoulder straps over miles of steep terrain. At 6.1 oz, this is not a heavy-duty work shirt, but for early season backcountry hunts with 30-40 pound packs, the Core Merino 120 is field-tested to handle the abrasion that destroys standard merino after a single trip.
