Boasting three layers of GORE-TEX ePE fabric, you get GORE-TEX performance with a lighter weight. Comfier, less bulky and easier to pack. Handy for those rainy bike-to-work days, long hikes or mountain escapades, right? But we know things can get tough out there. Which is why we use heavier GORE-TEX around the knees and butt – high-wear places that crave reinforcement. Max durability. Minimal weight. For many adventures.
