Strenuous activity is supposed to be uncomfortable—but Smartwool® base layers can help reduce some of that. Meant to layer under shorts or pants, our Women’s Intraknit™ Base Layer Bottom is designed to help with moisture management and temperature regulation. It’s built with a blend of responsibly sourced Merino wool and TENCEL™ Lyocell fibers, making a performance fabric which helps with cooling. Plus, it offers a fit that moves with your body, mesh ventilation to help keep you dry, and minimal seams to help reduce chafing. With this bottom, you have fewer distractions to keep you from going at your workout with top-notch intensity. So go ahead and get after it!
