Great support, but fits small.
I wish the sizing chart would give complete sizing.
I needed a 22 for my knee but the steel plates dig into my calfs making it impossible to wear for long periods.
Too bad because it feels and gives great support.

Very good for football
I bought this Pro Stabilizer for football because people online said they liked it. It fits great and it's got high quality neoprene. It provides my knee with a lot of support when i'm cutting at football practice. Well worth the price.
