Ready for deep powder days, shoulder-season backpacking trips and frosty hikes or snowshoes, the Zone One Sheep Suit is full-coverage battle armor against cold conditions, any time of the year. Icebreaker's all-new BodyfitZone construction uses strategically mapped insulation and breathable panels for intelligent temperature regulation, and the shaped hood and deep front zip help make small adjustments. Icebreaker built the Zone One Sheep Suit with a fully gusseted construction and contrasted, flatlock stitching to offer unrestricted, chafe-free movement when you're skinning uphill or romping down through the trees. The suit's breathable panels feature Icebreaker's corespun fabric, which uses nylon fibers wrapped in Merino to increase durability and retain next-to-skin softness. And when you're out enjoying Mother Nature, the front fly and back flap with a two-way zip make it easy to answer her call.
