"What Our Gearhead® Experts Are Saying:""These bibs nail the balance of waterproof protection, breathability, and durability—perfect for resort days or big backcountry missions.""The Stio Environ Bibs are built for skiers and riders who thrive in deep snow, shifting weather, and high-output days on the mountain. From inbounds powder stashes to backcountry lines, these shell bibs provide the waterproof confidence and breathability you need to keep charging when the storm rolls in. A regular fit keeps them comfortable for layering without extra bulk, while a high-waist bib design seals out snow where jackets and pants can’t. Engineered with PeakProof™ 3L recycled polyester fabric, the Environ Bibs deliver 20K waterproofing and 10K breathability, complete with fully taped seams for storm-level protection. Outseam venting regulates heat on the climb, articulated knees and an action gusset keep your stride natural, and internal boot gaiters lock out snow on deep days. CORDURA® kickpatches protect against ski edges, and a drop-seat feature adds convenience. From dawn patrols to closing bell, these bibs are made to keep you dry, durable, and ready for every turn."
