Built for deep snow and steep lines, the award-winning Environ Bib is our fully featured waterproof ski bib that provides premium weather protection on either side of the gate. Our seam-sealed and waterproof/breathable PeakProof™ recycled face fabric is super durable for day-in, day-out use, and the Environ’s high waist and suspenders provide optimal performance when hiking and ample coverage in the blower conditions you dream about. Side zip vents with YKK® water-resistant zippers let you ditch excess heat and also double as a drop seat. Articulated knees, a stretch back panel and a gusseted inseam improve freedom of movement on skin tracks and cliff drops. The zip hand pockets and a zip thigh pocket stash your pass, phone and other on-mountain essentials.

As caretakers of the mountain life, we recognize our responsibility to support organizations and people who share our vision to drive positive change for people and the planet. We’re proud to partner with some tremendous organizations in their missions to responsibly advance outdoor recreation and protect our wild surroundings.
We are committed to building garments that are durable, timeless and continue to perform season after season. After years of research, testing and product development, in 2024 we completely removed PFAS from all of our newly developed products. We remain committed to growing our Preferred Materials usage, which includes organic cotton, recycled materials and responsibly-sourced down and wool, to 75% by the end of 2025.
Our apparel is built to last. As a part of our efforts to reduce waste and keep more gear in the mountains where it belongs, our home-grown gear renewal program allows previously-used items to be traded in, cleaned, repaired and circulated back into use.
