It's crafted using the moisture-wicking HeatGear® performance fabric that draws sweat away from your skin to keep you cool and dry. The anti-microbial fabric technology prevents odor-causing agents from gaining a foothold on the garment, while the UPF 30+ UV protective properties shield your skin from harmful sun damage.
