Patagonia Triolet Pants

The pants that go where hardshell pants are supposed to go.

Same construction as the Triolet Jacket — 3-layer GORE-TEX ePE fabric, built for serious alpine conditions. Articulated patterning and a gusseted crotch for full range of motion on a steep bootpack or mixed climbing pitch. Full-length side zips let you pull them on over boots without sitting in the snow.

Internal gaiters with scuff guards seal out snow on technical terrain. Waterproof hand pockets. RECCO reflector. These are the details that matter when the terrain gets serious. If you're buying the Triolet Jacket, these pants complete the system.

Best for: Mountaineering, ice climbing, ski mountaineering, serious alpine objectives. Not for: Casual resort days — they're heavier than needed and overkill for the chairlift. Fit: True to size. Adjustable waist tabs allow for a customized fit over different baselayer weights.
