From big routes in the Canadian Rockies to ice park laps in Ouray, the Black Diamond Heavyweight Softshell Pants are our go-to bottoms for streamlined alpine climbs and winter ice cragging. Made with a durable yet highly breathable four-way stretch softshell fabric, the Heavyweight Pants feature a streamlined, contoured fit that layers easily, as well as a cinch adjustment with cord grommets at the ankle to keep out snow and avoid crampon snags. Harness-compatible pocket storage keeps your essentials close at hand, and the minimalist waistband and ladder-lock elastic waist helps you dial in the perfect fit to accommodate variable layers and also is harness compatible.
