Product Info

Watching seasoned backcountry travelers cut the ends of their toothbrushes and spoons to cut weight, you're thinking there has to be a better way. Patagonia has made it possible with the Patagonia Capilene Thermal Weight Boot-Length Pants. Warm and breathable and with minimal bulk, this base layer is built to meet your calf right where your socks and boots end. 92% recycled and bluesign® approved, this custom-cut pair has a 22" inseam for a comfortable wear that is primed for any big mountain challenge.

Product Details


3.8-oz Polartec® Power Grid™ | 92% Recycled Polyester / 8% SpandexPolartec® Power Grid™ was created to push the performance of base fabric technologies even further. By developing a patented grid design structure Polartec discovered a new way to reduce fabric weight while increasing warmth and compressibility in the process. This grid construction enhances both wicking efficiency and breathability by generating channels of targeted touch points that absorb and diffuse moisture vapor for faster evaporation.
