Our USA Tuna performance tee is based on the Hydroflex Short Sleeve, except we use raglan sleeves for a better all around fit in a long sleeve. All Hydroflex shirts feature our Proprietary UV50, 360 Flex Stretch speed dry fabric, which we brushed for the ultimate hand feel and added stretch for ultimate mobility and comfort. You may be hard pressed to believe this is a performance fabric and not cotton. This garment features the White Water logo on the chest. Woven Icon branding at the hem.
