The Sitka Core Merino 120 Bottom is an ultralight merino base layer designed to be worn under your trousers on warm-weather and early-season stalking trips, when a full-weight thermal would leave you overheating on the hill. Built from 120-gram, 17.5-micron ArmorSpun merino wool, it combines the natural odour resistance of merino fibres with genuine next-to-skin softness, helping you stay undetected on a stalk while avoiding the itch some wool base layers bring. The wool blend also regulates temperature well beyond its low weight, moving with you through a hard climb and a long, still glass in equal measure. ArmorSpun reinforcement adds durability that plain merino often lacks, so the garment holds up to repeated wear and washing over several seasons rather than pilling and thinning after one. Low-profile flatlock seams sit flush against the skin, avoiding the chafing a bulkier stitched seam causes under close-fitting trousers or waders. At just 4.7oz it barely registers in the pack, and unlike many merino garments it can go straight into the regular wash rather than needing hand-washing and careful drying between hunts. Practical, quiet and genuinely low-maintenance base-layer kit.
