The ​SFAST is a simple, patented, innovative solution to shoulder joint instability. Previous shoulder-bracing devices have been known for being difficult to fit and adjust. The ​SFAST ’s one-piece structure utilizes a polyurethane strap configuration that mimics the body’s natural movement while maintaining dynamic end-range-of-motion support. This simple-to-fit design allows the brace to be adjustable and provide long-lasting stability.

Functional Stability™

What if there was a way to limit the potential for injury while still elevating your performance? Current bracing standards rely on joint restriction and the transfer of impact to prevent injury; compromising healthy joints and causing additional injuries. Our solution is to limit impact at the source and reduce future injuries through functional stability. Functional stability maintains the proper kinetic chain and offers optimal support at the affected joint’s end range of motion without inhibiting performance. By utilizing functional stability, our bracing provides dynamic support that delivers superior, elevated results.

  • Limits injury
  • Stabilizes joints
  • Provides dynamic support
  • Mimics the body's natural movement
  • Delivers protection without inhibiting performance
  • Offers a range of motion support
