The Sonic Ultra Tee is a responsive, lightweight tee for mountain runners pushing performance. Slim-fitting and adaptable with built-in stretch, it’s ideal for running on sunny mountain days or tackling challenging inclines. Highly responsive to your output, it’s cleverly designed to regulate your temperature. Built with ultralight Motiv™ Aero fabric, the Sonic Ultra Tee is fast-drying, quick-wicking and highly breathable. With its subtle mesh structure, the fabric wicks moisture away from the skin, keeping you dry on intense climbs. Laser cut vent holes in high heat areas dump heat quickly and keep the air flowing. Ideal on its own for running in the heat, or for layering over as you climb to higher altitudes and exposed terrain.
