The Environ Jacket is built for those who chase storm days, steep chutes, and big lines from open to close. Designed with Stio's PeakProof® 3-layer recycled polyester shell, it delivers durable waterproof protection while maintaining breathable comfort for high-output mountain missions. A soft tricot backer keeps the interior cozy without compromising performance, and the articulated sleeves ensure a natural range of motion on the skintrack or the chairlift. Ventilation pit zips help regulate heat, while a helmet-compatible hood and powder skirt offer full coverage on deep days. From resort laps to backcountry bowls, this jacket is made for weather that does not mess around.
