Durability you can trust with advanced cooling technology. Powered by the Polartec Delta fabric, the Delta Long Sleeve regulates dry times and allows better breathability when wet. It's like wearing a mountain bike jersey with a built-in radiator, and it keeps you cooler. The cooling tech is combined with strategically placed abrasion-resistant zones for coverage from trail overgrowth.
