Maximizing comfort on long spins and fast paced training rides, the Velocio Men's Stripe short sleeve jersey features a nylon elastane blend for a light, airy feel with ample stretch. It's rated at UPF 50, ensuring maximum protection from harsh UV rays. Furthermore, you'll find its race specific cut provides a close to body fit without restricting motion. Mesh side panels improve ventilation by channeling cooler outside air over your body. Its silicone waist gripper prevents the jersey from riding up when you're dropped over the bars. Plus, you'll find four pockets at the rear, one of which is zippered, for conveniently holding energy gels, nutritional snacks, and extra layers. And because it's made in Italy, this jersey is of the highest quality, fit, and function.
