On a lift-served day that mixes groomers, steeper pitches, and a short hike to the ridge, the Stio Environ Bib Pant is the waterproof ski and snowboard bib pant that keeps up. This season's updated PeakProof membrane breathes better while holding the same waterproof standard, and the 3-layer recycled polyester shell is fully seam-sealed. A mid-height bib with a stretch-woven panel and elastic suspenders covers the torso without adding bulk. What Our Gearhead(R) Experts Are Saying:"The side zip vents let heat out on the hike to the ridge, and they doubled as a drop seat for a break at the top. Through the steeper pitches, the articulated knees and stretch back panel moved with me, so nothing pulled at the knees or back."
