On a sidecountry day that starts with booting up a line before the first turn, the Stio Environ Jacket is the waterproof ski and snowboard shell jacket that keeps pace. An updated PeakProof membrane lets more moisture out, while the 3-layer recycled polyester fabric stays fully seam sealed against wind and wet. The helmet-compatible hood adjusts at the front and sides and comes off when the day warms up, and with no insulation in the shell, warmth is a layering decision. What Our Gearhead(R) Experts Are Saying:"Opening the pit zips at the start of the boot-pack kept my base layer dry all the way to the top, and the membrane moved out the rest of the moisture. I zipped them shut at the transition, and the shell stayed comfortable through the descent."
