DC COMICS Compression Shirt
Applying a balanced surface pressure over specific body parts triggers an acceleration of blood flow, increasing oxygen delivery to muscle groups being worked to enhance their performance.
The circulation improvements also help the body reduce the build-up of lactic acid and other metabolic wastes. The combination of these effects allows you to work at a higher rate for longer periods.
Another benefit is the fabric's ability to draw moisture away from the body, keeping you warmer in the winter and cooler in the summer. As an added bonus, these garments can be made with anti-bacterial material, which means even though you're sweating, you're less likely to have the undesirable side effect of body odor.
And, because the items are sleek, and black is the preferred color, many people not only feel good wearing compression workout gear, they also look good.
