You need a jacket that’s been tested in the steep and deep ski runs you love. That’s why the Stio Environ Jacket exists, to protect you from the elements when fun is the priority. With Stio’s highly reputed PeakProof 3L construction, this jacket is super weatherproof and easily layerable on warmer days thanks to its non-insulated shell. Made to function for years, it is fully seam-sealed and backed by waterproof zippers on every exposed opening. Pit zips, pockets, a powder skirt, and a removable hood add customization, so you can be prepared for whatever the mountain has in store.
