Featherlight yet bombproof, the Mammut Eiger Free Advanced HS Pant is a trustworthy backcountry counterpart to skiers, snowboarders, and alpinists. The GORE-TEX laminate wicks moisture and dumps heat as it seals out the weather, while the strategic cut and pre-shaped knee sections ensure that we can move feely up skintracks, rocky outcroppings, and ice walls.
