About Compression Zone Technology®

At OS1st, our goal has always been to innovate new products and technologies to help people manage their pain and injuries. We want everyone to feel better for longer.

When realizing that the market was filled with heavy, hot, expensive, and hard-to-wear solutions, our founder, Dave, drew on his experience knowing that there had to be a better way. That’s why OS1st developed lighter, easier-to-use compression technology—and went even further by making it comfortable.

The QS4® ITB/Quad Bracing Sleeve with ITB brace is one-of-a-kind as it combines all the benefits of medical grade orthopedic support and graduated compression to ease and prevent Iliotibial Band Syndrome. Powered by Compression Zone Technology® the QS4 is effective while still being easy to take on and off, light and comfortable to wear even under any active-wear clothing or gear.
