Anti-odor technology prevents the growth of odor-causing microbes to keep your gear fresher, longer. 30+ UPF protects your skin from the sun's harmful rays. Smooth flatlock seams prevent chafing. Durable heat-sealed UA logo on front and back lockertag so you can mark your gear. 5.0 oz. Polyester/Elastane. Imported.

Work out harder and longer without feeling bogged down with the Under Armour HeatGear men's long-sleeve compression top. The shirt is made using HeatGear technology, a superior moisture-management system that moves moisture away from your body to the outer layer of the garment.

The long-sleeve shirt's compression fit helps maximize your workout performance.

This allows the moisture to evaporate quickly, keeping you cool even on extremely hot days. The shirt's compression fit, meanwhile, bolsters muscle support and increases circulation during workouts, resulting in a higher efficiency output and increased stamina. And hard-training athletes will love the shirt's anti-odor design, which prevents the growth of odor-causing microbes. Other features include a smooth design that reduces abrasion in high-impact areas; a 30+ UPF rating that protects your skin from the sun's harmful rays; a Heatseal logo; and a back locker tag. Made of 81 percent polyester and 19 percent Elastane, the shirt is available in a variety of colors and sizes.

About Under Armour
It started with a simple plan: Make a superior T-shirt, a shirt that provided compression and wicked perspiration off your skin rather than absorbing it, and that worked with your body to regulate temperature and enhance performance. The plan evolved into a full-fledged commitment to producing performance apparel engineered to keep athletes cool, dry, and light throughout the course of a game, practice, or workout.

Founded in 1996 by former University of Maryland football player Kevin Plank, Under Armour offers a diverse product assortment of performance gear for men, women, and youth, with an intuitive product framework that's easy to understand: wear HeatGear items when it's hot, ColdGear when it's cold, and AllSeasonGear between the extremes. Under Armour's mission is to provide the world with technically advanced products engineered with the company's superior fabric construction, exclusive moisture management, and proven innovation. Every Under Armour product has a specific purpose--to make you better.
