Designed for wicking warmth in cold conditions, this baselayer delivers soft-on-skin comfort and exceptional thermal regulation thanks to its powerful merino fabric blend.

Peak performance starts at your base, and this crew is the perfect foundational layer when cold conditions call for extra warmth and exceptional breathability. The foundation of its unmatched performance and next-to-skin comfort is our proprietary PeakWool™ fabric, a powerful blend of soft yet resilient Tencel, nylon and elastane fibers with the warmth and wicking of 56% merino wool to deliver strength, comfort and range of motion for cold days on the mountain. Flatlock seams minimize friction and thumbholes enable easy layering.

PeakWool™ is a midweight fabric constructed with Merino Wool, Tencel, Recycled Nylon and Spandex. The natural properties of Merino regulate body temperature, keep odors at bay and manage moisture to keep you dry. The addition of synthetic fibers increases softness, adds strength and elevates its wicking properties. PeakWool™ excels in cold temps by keeping your core warm and dry, while enabling heat transfer when the tempo picks up.
