UA Compression shirts aren't just for looks. That second-skin snugness actually works to increase your stamina, muscle control, and overall power-making you a well-oiled machine on the course. Our Compression shirts also enhance proprioception, your body's muscle memory and spatial awareness-meaning your swing will be smoother, more consistent, and, ultimately, more accurate. Which all boils down to a lower score and a higher awesomeness ranking. Two things a good golfer always looks for. But after the front 9, even the most awesome of golfers can get a fatigued core from excessive lateral bending and twisting. So we created Men's Shortsleeve Armour® Stability T-shirt. Designed specifically for golfers, it helps stabilize your core-keeping your muscles fresh and preventing lower back injuries. And because our gear is built to do more-the Men's Shortsleeve Armour® Stability T-shirt also features strategic vent zones that dump excess heat, so you can always keep your cool on the course.
