Deep snow stays outside the Mammut Eiger Free Pro HS Bib Pant, a 3-layer hard shell with a fixed bib and integrated snow gaiters. GORE-TEX Pro makes these bib pants waterproof, windproof, and breathable in stormy conditions, and adjustable leg width tunes the fit at the hem. Dyneema reinforcements add durability to the shell. What Our Gearhead(R) Experts Are Saying:"I open the side zippers a few minutes into a skin track, and the heat clears out before it soaks my base layer. The pant has no insulation, so I add or drop a layer underneath to match the day, and the shell stays on from the car to the summit."
