Optimize your trail running performance with an ultralight, breathable T-shirt, thanks to the hybrid design of the INTENSE technical T-shirt for men by MILLET. It combines two DRYNAMIC stretch fabrics, with a particularly breathable construction under the arms and in the back to accelerate moisture wicking. The short-sleeve, round-neck cut has offset seams at the shoulders to avoid chafing caused by wearing a backpack. And when you're running at night, the reflective elements on this trail running shirt maximize your visibility.
