Flex Pants


After a year on the U.S. market, Adidas has been looking to make a splash in climbing apparel, and the German giant just might do it with the Terrex Swift Flex Pants ($95; adidas.com/us/outdoor). Made with stretchy, lightweight, synthetic fabric, this elegant and simple pant has no unnecessary stitching, pockets, or “features” all too common on other climbing pants. During high-output alpine endeavors in Rocky Mountain National Park, the breathable fabric did the trick during approaches, while shedding light snow and staying warm and dry. For cragging and gym sessions, the Flex moved and stretched with ease, never restricting movement. Also appreciated was an integrated belt that sits well under a harness and keeps the pants from sagging. One drawback was some slight pilling in the material on the knee panels after the first wash, but it never worsened with additional washing and continued abrasion. —Maury Birdwell
