From backcountry to sidecountry to resort, the Environ Pant is designed to handle the most demanding winter pursuits from backcountry to sidecountry to resort. Constructed with PeakProof™, a waterproof/breathable recycled face fabric, the Environ is a resilient, fully seam-sealed all-mountain pant. Abrasion-resistant CORDURA® kickpatches offer enhanced durability and internal boot gaiters keep snow out. Outseam venting provides climate control, while articulated knees and an action gusset allow for full range of motion.

In our outdoor world, not all shell fabrics rate the same, which is why we decided to set a Stio® standard for mountain-rated protection you can trust when rough weather descends. Our new PeakProof™ rating ensures a Teton-tested level of waterproof technology and breathable comfort for elevated action in mountain environments.

We completely offset the footprint of each order through our commitment to being climate neutral. As part of our mission we value being good caretakers of the mountain life and protecting the places where we play.
We are committed to building garments that are durable, timeless and continue to perform season after season. Over 50% of our product line incorporates preferred materials, which include organic cotton, recycled materials and responsibly-sourced down. We are committed to growing our preferred materials usage to 75% by 2025.
We believe a circular commerce system will design out waste and pollution, allowing for used clothing to be renewed and put back into use. Stio Second Turn™️ is our gear renewal program that allows customers to trade in and shop used apparel.
