Introducing the Under Armour Men's HeatGear Mock Long Sleeve Baselayer, your new go-to performance gear. Crafted with the perfect blend of style, comfort, and durability, this baselayer is designed to be the first thing you put on and the last thing you take off. This high-performance baselayer is made from our original HeatGear fabric, a tough yet lightweight material specifically engineered for superior performance and comfort. Comprising 79% Polyester and 21% Elastane, the fabric offers all the benefits of Under Armour Compression. It fits like a second skin, providing ultra-tight compression that enhances your performance and speeds up recovery time. One of the key features of this baselayer is its sweat-wicking ability. The material not only wicks sweat but also dries really fast, ensuring you stay comfortable and dry no matter how intense your workouts get. Plus, it comes with stretch-mesh back and side panels for strategic ventilation, keeping you cool when the heat is on. We've also given it a mock neck construction for added coverage, keeping you warm during those cold morning runs or late-night training sessions. The updated ergonomic design ensures that seams stay off high abrasion areas, significantly increasing durability and ensuring your baselayer lasts longer. Another unique feature of this baselayer is its easy-care instructions. All you have to do is wash the garment inside out in cold water with like colors, tumble dry low, and avoid ironing, using softeners or dry cleaning. This ensures your baselayer retains its quality and performance for a long time. Whether you're hitting the gym, going for a run, or practicing for the big game, the Under Armour Men's HeatGear Mock Long Sleeve Baselayer has got you covered. It's not just a piece of clothing; it's a performance gear designed to enhance your athletic performance and keep you comfortable in all conditions. Choose Under Armour for quality, performance, and style.
