Smartwool layers work as well for our workout warriors as for our freeze babies! Meant to layer under shorts or pants, the 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 that helps with cooling. Plus, it offers a very close fit that moves with the body, mesh ventilation to help keep you dry and minimal seams to help reduce chafing.
