The Patagonia M10 Storm Pant brings futuristic technology to ancient mountains, delivering a highly functional pant for climbing snowy, icy peaks. The pants have a unique construction with a four-point gusset at the crotch and articulated knees for maximum freedom of movement while we're methodically making our way up towering walls of ice, and the elasticated waistband sits comfortably beneath our harness. The single thigh pocket is designed to be easily accessible even when we're in technical terrain, and the elasticated cuffs tuck into integrated gaiters on alpine boots for a streamlined look and feel. The pants are made with Patagonia's reliable 3-layer H2No membrane, which efficiently allows heat and moisture to escape while ensuring melting ice doesn't seep into our baselayers while we're pressed against cold sheets of ice, and a DWR finish ensures the pants don't wet out while we work our way across deep fields of snow.
