A lot of professional athletes swear by these posture correcting shirts. The Intelliskin is the result of years of applying tape to pro athletes and noticing astonishing results when soft tissue injuries were aligned in a specific direction and force. Since tape don't last more than a few days, the Intelliskin was born. They straightens you up, improve your breathing, and help maintain proper weight distribution. Slouching becomes uncomfortable. Some athletes credit the IntelliSkin as an important component in their award-winning performances.
