Excellent fit , Great protection

Excellent fit , Great protection
I am 5’10” average build. I bought an extra large set of knee pads. They fit perfect. Very very comfortable . I had them on for 5 hours and could have worn them on our drive home (3 hours) they are so comfortable. I don’t even need to tighten the Velcro. I bought these over other brands because of the Velcro just in case. I crashed hard at an indoor bike park ( wooden ramps) my first time using them. I landed into the side of the ramp on a sharp edge. These pads held up. No rips or tears. I have no doubt my knee would have been really messed up without this protection. Just for clarification, I’m a 50+ y.o. guy. I’ve ridden bmx and mountain bikes my whole life. Crashes get a little harder to recover from the older I get so I wanted some added protection with comfort. I looked at 3 other brands and kept going back and forth. I finally decided on these. I am completely satisfied
