Review on Leatt Airflex Pro Knee Guards-Black-L: Ultimate Protection and Flexibility for Extreme Sports by Bryan Ramirez

I have no issues with the pads themselves. They appear well made and durable. My problem is that according to the size chart they were too small for me. I ordered XL and my thigh size is 19 3/8 inches, 3-4 inches above the knee and 16 inches at the calf. These are fine within the size range, but I found them so tight that circulation was cut off. I would say that you should aim for the size that fits the smallest part of the measurement. I will go back and look for an XXL replacement.
