When the mountains turn serious and the weather won't quit, the Patagonia Triolet Jacket delivers the bombproof protection alpine climbers and mountaineers demand. This technical shell harnesses 3-layer GORE-TEX ePE Performance fabric to create an impenetrable barrier against wind, snow, and driving rain while maintaining the breathability you need during high-output ascents. The helmet-compatible hood features a laminated visor that sheds precipitation and maintains visibility whether you're navigating a whiteout or threading a technical ice route. Smart design details like harness-compatible pockets and watertight pit zips ensure your gear stays accessible and your body temperature stays regulated, even when you're locked into a steep pitch with a full rack. Built with 100% recycled materials and PFAS-free construction, this alpine workhorse proves you don't have to compromise your values to conquer your objectives – it's ready to be your trusted partner through countless cold, snowy adventures where failure simply isn't an option.
