Therma Shell™ T-Shirt
Accelerate Your Sweat, Elevate Your Training
Engineered for fitness enthusiasts and athletes, the Therma Shell™ T-Shirt is built to work harder alongside you. Its heat-trapping polymer lining sits beneath a soft, athletic-fit outer shell — designed to raise core temperature during movement and support increased sweat production while you train, all without restricting your range of motion.
