With a lightweight, breathable design, the Outdoor Research Skytour AscentShell Bib Pant is perfect for backcountry skiers looking to move fast on the skin track. The AscentShell membrane is permeable to air but blocks water from sneaking in and drenching our baselayers. The durable bibs feature reinforced cuffs to protect against the edges of our skies, with plenty of stretch so we can move naturally on the way up or down the mountain.
