Thunder Pant came to life because we were tired of getting soaked in Squamish. The rain comes from all angles in British Columbia's wettest town, and while our tops were toasty, our legs needed shelter. So we started working on fully waterproof trail longs that wouldn't stand out as being anything other than awesome adventure pants - until it rains.

We made Thunder Pant with two different weights of GORE-TEX PRO fabric to offer impregnable water protection, best-in-class breathability, and exceedingly high levels of durability in repeat friction areas like the seat and upper legs. And it's built to put on while wearing shoes - even over other pants - thanks to the velcro-secured stretch fabric at the end of the legs, and watertight zippers. A fly-free front gives way to stretch panels and straightforward side buckles at the waist to help dial in a perfect fit.

But what about your legs? We noticed through careful analysis that people have different leg lengths. So in the spirit of choose-your-own-adventure, we left the length up to you. Go for a spin, and if there's too much Thunder, trim the hem with scissors along the pre-marked lines.
