The Sonic Ultra Tee is fast-drying, quick-wicking and is highly breathable. It’s cleverly designed to regulate your temperature, made using quick-wicking Motiv™ Aero fabric that’s highly responsive to your output. The fabric wicks moisture away from the skin with its subtle mesh structure, keeping you dry on intense climbs. The laser-cut vent holes in high-heat areas release 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.
