Size matters. Mine fits perfectly - doesn't budge, doesn't bind, and offers just the compression I need to help deal with a knee injury. ### ⭐⭐⭐⭐⭐ Great product. Good support *by on Reviewed in the United States April 14, 2017* Great product. Good support. Really light and breathable. I use this when I work. I have a very physical job with alot of walking. This does the job for me. No slip, Grips nicely to your knee and leg with the rubber pieces on the inside. This is my favorite compression sleeve I've had. Works well at the gym while running on the treadmill and elliptical. ### ⭐⭐⭐⭐ Good fit.
