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™ moisture management, ActiveFresh™ 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.FeaturesFABRIC PERFORMANCE Wicking Quick Drying Breathable Odor Resistant UPF 15 DESIGN FEATURES Fold-over Mitt Cuffs Flat-seam Construction Reflective Logo Raglan Sleeves FUNCTIONAL DETAILS Fold-over Mitt Cuffs Flat-seam Construction Reflective Logo Raglan Sleeves Specs FABRIC: Airvent™, 100% polyester CENTER BACK LENGTH: 27 ½" / 70 cm WEIGHT: 2.3 oz/64 g
