The Men's Patagonia Endless Run Tight is formfitting and made from a quick-drying power-stretch knit fabric that blends recycled nylon with spandex to support both movement and sustainability. Treated with miDori bioSoft for added wicking and softness and HeiQ Mint for odor control, this tight is built for extended trail runs. Two no-bounce side pockets provide secure storage for a phone, snacks, or a map, while a soft, flat elastic waistband enhances comfort. An external drawcord allows for a customizable fit, and pique-mesh panels behind the knees improve breathability.
