Arc'teryx Men's Velox Crew SS

Keep running up the trail in summer's hot temperatures with the Arc'teryx Men's Velox Crew keeping you comfortably cool. Unlike breathable fabrics that start breathing after you work up a sweat, this crew's air permeable Libro fabric starts to breathe the moment you put it on. Arc'teryx designed this superlight shirt with smooth flatlock seams to reduce chafing.
