Support your knee with the OS1st KS7 Performance Knee Sleeve. Seven zones of graduated compression support the knee and help relieve pain from Runner’s Knee, Patellar Tendonitis, and Arthritis. OS1st’s ultra-thin design allows this knee sleeve to be worn under full-length pants for all-day comfort. Whether you need extra support to get through your next run or are focused on compression-based recovery after your workout, the OS1st KS7 Performance Knee Sleeve delivers the support you need.


If we’re running or walking with a knee sleeve, we don’t want something big and bulky that will get in the way. We’re already dealing with knee pain, so the solution shouldn’t create more problems. The OS1st KS7 Performance Knee Sleeve provides compressive support to the knee for stability and recovery with lightweight ultra-thin construction that allows you to move unencumbered. It’s thin enough to wear under jeans or dress pants, so you can promote circulation and recovery as you go about your day.


  • Unisex sizing – see chart below to find the perfect fit

  • Compression Zone Technology – seven zones of graduated compression stabilize the knee and improve circulation

  • Seamless construction – no seams for a comfortable, chafing-free fit

  • Moisture-wicking fabric – soft fabric stays dry on the run or over a long day of wear

  • Ultra-thin design – fits easily under any apparel
