On Climate Shirt Men's – Brume

A running top for cold days, built with On's ThermaTec fabric. The idea is warmth without bulk: it keeps heat in while staying breathable, and it moves sweat away from the skin so you don't get cold once you've warmed up. A fitted cut, so it sits close and works well as a base under a jacket.
