Zetti Long Sleeve Shirts Mens Sports Compression Layer Skin Tights Fitness T-Shirts Enhanced Muscle Recovery and Performance: This Long Sleeve Compression Shirt features advanced compression technology to provide support to muscles and improve circulation. Improving circulation in the upper body helps to supply your muscles with more of the oxygen they need to recover from hard workouts. It also helps to improve muscular endurance, as well as power. It can also be used to rehab and prevent injuries, as the compression helps to stabilize muscles. Keeps Upper Body at the Perfect Temperature: The long sleeve compression shirt contains silver ions to provide thermal regulation. The silver ions help to regulate body temperature, ensuring you are never too cold or too hot. Wear the shirt while skiing in the winter or during the summer while playing golf. Seamless Second-Skin Fit: The Long Sleeve Compression Shirt utilizes an ergonomic tailoring design to provide the ultimate "second-skin" fit. The shirt is the perfect base layer. Whether using the compression shirt for working out, baseball, outdoors, basketball, running, golfing, skiing, hiking, or just during cold weather, the compression shirt fits perfectly under other shirts. Wear it without an additional shirt in the gym to show off your muscles or as a base layer to keep warm. Moisture Wicking, Anti-Odor, and UV Protection: The long sleeve compression shirt features UV 50+ protection. It is also moisture wicking, meaning it will not become heavy with perspiration. The fabric wicks sweat away from the skin through the compression shirt, where it evaporates into the air. Anti-odor technology in the shirt prevent the build of bacteria while wearing the shirt, allowing it to stay feeling fresh. Keeps Shape: The compression will keep it shape for many wears and washes. Whether wearing it while running, working out, or around the house, you can be confident the shirt will continue to perform.
