Train with the Arc'teryx Men's Trino Tight when fall brings low temperatures and rainy weather. Windstopper covers the front with wind resistant protection, while the DWR finish sheds rainfall to help keep you dry. Arc'teryx made the back out of Vistrasari in order to wick moisture, dry quickly, and provide a four way stretch. Articulated knees give you a full range of motion in these trim fitting tights, and flatlock seams keep chafing to a minimum on long runs. Arc'teryx also added a zippered lumbar pocket with a media port for your music player and a reflective logo to help keep you visible in low light.
