Engineered for the most demanding alpine conditions, where performance meets durability
When the Mountains Call
Every skier knows the frustration: you’re halfway up the backcountry ascent when your thighs begin to boil, or worse – a sudden storm soaks through your pants’ seams. Most resort-to-backcountry pants force compromises: either suffocating waterproofing or inadequate storm protection. The Stio Environ Pant redefines expectations with PeakProof™ technology that withstands Teton-level abuse while offering unparalleled breathability.

The Stio Difference
While competitors focus either on resort comfort or backcountry durability, the Environ Pant delivers both through intelligent material combinations and user-focused design. The PeakProof™ certification means these pants undergo real-world testing in Grand Teton National Park’s extreme conditions – a standard most brands can’t match.
From Struggle to Summit: The Environ Experience
The Problem
Jake, an avid backcountry skier, constantly battled between overheating during ascents and freezing during descents. His previous pants either lacked proper vents or compromised waterproofing at seams.
The Breaking Point
During a spring tour in the Rockies, Jake’s pants failed catastrophically – soaked through by wet snow during descent after the DWR wore off, then torn by sharp ski edges during a fall.
The Solution
The Environ Pant’s MaxVent™ system allowed temperature regulation during climbs, while the CORDURA® reinforcement withstood ski edge contact. The PeakProof™ membrane kept him dry through afternoon slush.
“After three seasons, my Environs look nearly new despite 100+ days of abuse. The thigh vents are genius – I can go from skinning to descending without stopping to adjust layers.”
