From mile repeats to cross training at the park, the PhD' Ultra Light Short Sleeve can handle your sweatiest workouts. Smartwool started with naturally breathable Merino wool to help regulate body temperature and naturally resist odor, then add polyester to increase stretch and recovery and decrease dry time. Side mesh panels give extra ventilation where you need it most.
