What Our Gearhead® Experts Are Saying: "I reach for these bibs when conditions are serious and failure isn’t an option. They’re impressively light for a full waterproof shell, layer easily underneath, and move well on steep terrain. For long alpine days where weather protection and efficiency matter most, they’re exactly what I want on." We pack the Dual Aspect Bib Pant for objectives that live above the tree line, where weather windows are short and conditions are unforgiving. Patagonia built these bibs for high-output alpine missions, combining full storm protection with a lightweight feel that doesn’t slow us down on long approaches, steep bootpacks, or technical climbing. The H2No Performance Standard shell blocks wind, snow, and driving precipitation while staying breathable enough for sustained efforts. A streamlined bib design adds coverage and security while allowing room for layering underneath, and stretch suspenders keep the fit comfortable throughout big days. Ankle-length side zips make transitions easier, while reinforced scuff guards and integrated gaiter details stand up to crampons, ski edges, and rugged terrain. Purpose-built for demanding mountain environments, these bibs are made for days when turning back isn’t part of the plan.
