Compression Zone Technology

Bringing together graduated compression and medical-grade orthopedic support, Compression Zone Technology® is the foundation upon which every OS1st® product is constructed. This groundbreaking technology delivers FDA-registered medical-grade support in lightweight, comfortable bracing sleeves and socks that are thin enough to be worn under your apparel of choice.

Utilizing anatomically correct zones of precise graduated compression, OS1st socks and compression sleeves surround your joints, muscles, tendons, and ligaments for 360 degrees of support. Compression apparel has been shown to enhance circulation, support and stabilize joints, improve performance, and aid in recovery, which means you can spend more time participating in your favorite activity and less time dealing with instability, pain, and injuries.
