Both measurements should be taken with you standing.

“Wearing my Armor braces gives me much more confidence when I jump, especially after my knee injury I wouldn’t even think about jumping without my Donjoy Knee braces”.

"Although I’m tempted to try riding without the braces, I am of the opinion that prevention is better than any cure (!) and ultimately because the short version is much more comfortable, fits in my boots and it protects me very well."

“After my LCL injury and operation in June 2005, DonJoy has always been on my side. After my injury and before the operation I used the Legend. After the operation I used the low profile TROM, post-op brace. During my revalidation period I used the Legend. Without a doubt, DonJoy’s innovative technology met my high expectations.”

“Armor by Donjoy knee braces are a perfect fit for my lifestyle, the state-of-art blowout protection provides the support and comfort I need to trust my gear”.
