The Mammut Haldigrat HS Bib Pant is always ready to answer the call when we're in search of deep snow. Using a DRYTechnology PRO membrane, these bib pants stand up for us with waterproof, breathable performance in wintry conditions while also allowing us to move freely on the ascent thanks to a lightweight recycled nylon fabric. Throw in the zippered leg vents, multitude of gear-specific pockets, and a fixed bib, and we're ready to get the goods from sunup to sundown.
