Built for backcountry exploration. The Spurr's 3-ply Dermizax® fabric makes it the most reliable shell we can offer in 2024. Backcountry tested in the Pacific Northwest and British Columbia, the Spurr is an ergonomically designed jacket that will keep you warm and dry on those rainy ski days when you're skinning up to access freshly fallen snow at the summit. You've undoubtedly been there before.
