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.
We completely offset the footprint of each order through our commitment to being climate neutral. As part of our mission we value being good caretakers of the mountain life and protecting the places where we play.
We are committed to building garments that are durable, timeless and continue to perform season after season. Over 50% of our product line incorporates preferred materials, which include organic cotton, recycled materials and responsibly-sourced down. We are committed to growing our preferred materials usage to 75% by 2025.
We believe a circular commerce system will design out waste and pollution, allowing for used clothing to be renewed and put back into use. Stio Second Turn™️ is our gear renewal program that allows customers to trade in and shop used apparel.
