Difficult to fully recover at base camp when your legs are shaking from the cold unless you brought the Western Mountaineering Men's Flash Down Pants. Featuring 850 goose down insulation , warming the lower body you'll get the best possible recovery on the remaining climb. And there's really no reason to leave them at home because these pants weigh less than half a pound and shrink to half the size of your water bottle.
The Flash model is equipped with an adjustable belt that fits comfortably around the waist and elastic ankle cuffs keep the pants in place and keep frosty air out. Western Mountaineering reinforced the seat so you can sit on your ass as long as you need until a quiet recovery is complete.
