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.
