Introducing the Under Armour Men's HeatGear Sleeveless Baselayer, the epitome of performance wear designed with the modern active man in mind. This is the original performance baselayer that you'll want to put on first and take off last, designed to enhance your performance in all types of athletic endeavors. The key to this top's performance is its super-light HeatGear fabric. It delivers superior coverage without weighing you down, ensuring you remain light and agile during your workout or sports activities. Designed to offer maximum breathability, it features strategically placed mesh underarm and back panels that provide ventilation, keeping you cool and dry even during the most intense activities. One of the most impressive features of this baselayer is its moisture-wicking material. This material wicks sweat away from the body and dries really fast, keeping you comfortable and focused on your performance. This is an essential feature for any intense workout or sports activities, as it prevents the discomfort and distraction that can come with sweat-soaked clothing. Furthermore, the Under Armour Men's HeatGear Sleeveless Baselayer is designed with an ergonomic focus. This means its seams are kept off high abrasion areas to increase durability. The hybrid raglan sleeve construction adds to the overall comfort and range of motion, making this baselayer an excellent choice for any athletic activity. The compression fit of this top offers an ultra-tight, second-skin feel that enhances performance by keeping muscles aligned and reducing muscle fatigue. This top also includes a write-in locker tag on the back of the neck for your initials or number, adding a personal touch to your sportswear. The Under Armour Men's HeatGear Sleeveless Baselayer is made from a blend of 84% Polyester and 16% Elastane for the body, and 92% Polyester and 8% Elastane for the mesh, ensuring durability, stretch, and comfort
