Engineered for long runs and high-intensity training sessions, the Ten Thousand Session Short is stripped down to the essentials so there’s nothing holding you back. The ultralight shell fabric has a barely-there feel that keeps your focus on the path ahead, and the stretch anti-chafe liner ensures you don’t have to tap out early due to discomfort. The experts at Ten Thousand added plenty of other details—like airflow-enhancing ventilation and smooth bonded hems—to help you manage more miles in greater comfort. And thanks to multiple low-profile zippered pockets, you still get plenty of storage without extra bulk.
