From deep days to ambitious ascents, our big mountain bib hangs tough. Exceptionally breathable GORE-TEX 3L PRO shell seals out winter’s strongest storms while a stretch woven upper adds core breathability.

From deep days on Teton Pass to ambitious ascents in Teton Park, our big mountain bib hangs tough when ticking the line is the driving force. Exceptionally breathable GORE-TEX 3L PRO Shell seals out winter’s strongest storms yet keeps a comfortable internal temp during heated skins or gripping two-axe climbs. A stretch-woven upper adds core breathability, while chest pockets stow supplies close at hand. YKK® Aquaguard side zips dump heat quickly, with one side separating fully to speed that morning ritual. A CORDURA® kickpatch withstands wear from sharp edges or points and the two-way zippered fly makes sub zero pit stops thankfully quick.
