Sikta Core Merino 330 Zip-Off Bottom

Built for bitter cold, changing elevation, and long days outside, the Core Merino 330 Zip-Off Bottom gives you heavyweight warmth without locking you into one setup all day. This high-performance base layer is made for very cold conditions and late-season backcountry use, helping you stay warm when glassing, hiking, or moving through shifting weather.

Its heaviest-weight merino wool blend delivers excellent warmth while still regulating temperature as your activity level changes. Natural odor resistance helps keep the layer fresher on extended trips, while reinforced ArmorSpun Merino Wool improves durability over traditional merino. Inside, a recycled synthetic lining pulls sweat away from your skin for dry, anti-itch comfort when conditions get harsh. And when it’s time to dump a layer fast, the zip-off design lets you remove it without taking off your boots—ideal for long expeditions, cold mornings, and unpredictable weather.
