Designed to break trail-running speed records, On Running's ULTRA-T is an ultra-light, high-performance men's trail top for ultimate comfort.
Made from ultra-soft recycled polyester fiber and ethane, this model is cool thanks to the mesh fabric at the back for ultimate breathability. What's more, all seams are smooth and taped to avoid pressure or chafing during intense exertion.
Additional features include a small pocket on the back for energy gels and other essentials, as well as reflective details.
