First of all the Rehband customer service is terrific. I made an error in ordering and returning. It looked like I was out of luck ending up with the wrong size knee sleeves. Rehband sent me an email requesting a review and I replied explaining what happened, all my fault. They replied that they wanted me to have the proper product and sent the correct sleeves out the next day along with a box of athletic tape at no cost. What a great company!
The RX Original 7mm knee sleeves work great. They support and stabilize my knees and allow me to lift heavier weights with more comfort and no knee pain.
Based on how well the heavy sleeves work, I ordered a pair of RX sleeves in 3mm for more general use. These provide support for lighter workouts and general exercise and are comfortable for longer sessions.
Both products get top ratings for functionality, durability and are easy to clean.
