Triolet Jacket - Women's

What Our Gearhead® Experts Are Saying:

"I wore the Triolet on a multi-day alpine route that threw everything at us, from driving rain on the approach to wind and snow on the upper mountain. The GORE-TEX kept me completely dry, the helmet-compatible hood stayed put in gusts, and the underarm vents saved me on the steep sections where the effort really picked up."

When the objective is serious and the weather is not cooperating, the shell on your back becomes one of the most important decisions of the day. The Patagonia Triolet Jacket is built for exactly those moments, wrapping the upper body in a three-layer GORE-TEX construction that delivers proven waterproof and windproof protection while remaining breathable enough to sustain high-output efforts on long alpine routes. Fully sealed seams close off every stitch line so sustained rain, driving snow, and freezing wind stay firmly on the outside.

The details reflect a jacket designed by and for people who spend real time in committing terrain. Gusseted underarm panels with two-way zip vents dump excess heat and moisture on steep bootpacks and skin tracks without compromising weather protection at the shoulders. A helmet-compatible hood adjusts two ways for a dialed fit whether you are climbing, skiing, or moving fast on exposed ridgelines. Internal chest pockets and hand pockets are positioned to stay clear of harness straps and hipbelts, keeping gear accessible without interference. An integrated RECCO reflector adds a layer of emergency searchability on high-consequence days in the mountains.
