High-exertion workouts and high temps don&';t always play nice together, unless you&';re rocking a piece from the Echo Collection. Built with UPF sun protection, AirVent(TM) moisture management, ActiveFresh(TM) odor control technology, and topped off with an anti-chafing flat-seam design, the Echo Collection is the smarter way to tackle the heat. This season, we&';ve trimmed down the fit so the Echo moves with you wherever you go. From sun-scorched desert climbs to sweltering ultra runs, the Echo is your perfect balance of tech-packed performance and ultralight protection.
