"What Our Gearhead® Experts Are Saying: ""I reach for this midlayer when I need warmth without overheating on the skintrack. The brushed merino feels soft against the skin, while the Tencel blend breathes better than pure wool. Thumb loops and gusseted panels make it a super functional piece I can wear under a shell or on its own.""When we need a midlayer that works as hard as we do, the Merino Blend 300 RealFleece Descender LS Zip-Top earns its spot in our kit. The brushed merino wool blend feels luxuriously soft while trapping heat close to the body, and the Tencel fibers regulate moisture when we start pushing uphill. Whether we’re setting out before dawn or moving fast in frigid temps, it gives us dependable warmth without weighing us down. Designed with movement in mind, this piece includes gussets for mobility, flatlock seams to prevent chafing, and thumb loops that keep sleeves in place under layers. Secure zippered pockets stash small essentials, while offset shoulder seams reduce pack rub. From ski tours to alpine climbs, it’s the versatile layer we rely on in cold conditions."
