The La Sportiva West Crest Pant layers an elastic waistband, snap button closure, and integrated belt to keep a secure fit through repeated days on trail, not just the first one. Slightly thermal fabric adds a touch of warmth for the temperature swings that come with high-altitude trekking, and cuffs with an elastic drawcord adjust as conditions change throughout a multi-day route. A trouser-to-shoe hook keeps pant legs in place through boot changes and gaiter use, so the fit stays dialed in from camp to summit. What Our Gearhead(R) Experts Are Saying:"I wore these for five straight days on a high-altitude trek and never had to readjust the waist once, even through temperature swings from camp to ridge. The trouser-to-shoe hook kept everything in place through every gaiter change too."
