Designed for efficiency and performance in trail running, On Running'ULTRA-T is an ultra-lightweight top for men that confère comfort and breathability during your intense efforts.

Made from ultra-soft materials based on CoolPlus® recycled polyester fibres, this model has a second-skin effect and gives you a huge feeling of breathability. What's more, all the seams are flat to avoid pressure or chafing during training.

A few details add to its functionality, like the big logo on the back and the reflective polka dots that increase your visibility once the sun goes down.
