Primed and ready for sidecountry hits, all-day tours and storm laps in the resort, this jacket is for the minimalist who never uses his powder skirt and the purist who knows exactly what he needs.

The latest addition to the award winning Environ collection, the XT is built for the minimalist who never uses his powder skirt and the purist who knows exactly what he needs. Without sacrificing an ounce of durability and protection, the XT offers a streamlined feature set with high set hand pockets for easy access when wearing a pack. Built with the same fabric as the award-winning Environ Collection, the XT features 3L Dermizax® waterproof/breathable fabric and is tough enough to take a beating, but still rolls up nicely for stashing in your pack. Cohaesive™ cord-lock technology on the hood and hem allow for one-handed adjustments and two-way underarm zip vents ditch excess heat. The fixed hood with a bonded brim fits over your helmet in full-on conditions and we added a zippered chest pocket, internal zippered pocket and drop-in stash pockets to secure your phone, gloves and other essentials.
