Excellent knee sleeve
I have Grade 3 Chondromalacia and many movements that involve knee flexion are uncomfortable, resulting in swelling and instability. The Rehband RX Knee Sleeve applies enough support, compression and warmth to allow me to train with minimal discomfort, clicking/grating and swelling.
I was sized right on the cusp of two sizes and I opted to go for the smaller of the two. This turned out to be the right decision as the knee sleeve stays in place for the entire workout, regardless of what that workout is, and I believe that if I had gone for the larger of the two sizes, it wouldn't have provided the level of support that it does.
I couldn't recommend this product more highly for anyone who needs increased support in their WODs.
