No matter the aerobic or endurance pursuit, our Basis®️ Seamless Tech Tight manages moisture, enhances comfort and reduces friction. Featured on Outside's List of The Best Women's Baselayers of 2023.

It’s set apart from the pack, or the peloton, due to a circular knitting technique that sheds seams, enhances stretch and creates breathable airflow zones to regulate body temps during hard workouts. Athletically matched to long runs, extended rides or uphill skis, the poly knit blend wicks moisture and regulates temperature to maintain a comfortable core when dialing up the intensity or pushing the pace.
