I really like the McDavid brand of braces. I was looking for something with a hinged support and this one is great! That being said, I did add an additional strap around the metal supports to make them more snug to my knee. That was necessary for me to get the fit I was looking for. I really like this brace though and would definitely recommend McDavid as the brand of choice for anyone seeking a brace or additional support. Quality products and a good fit. I wear this to play baseball and ice hockey and it gives me great support.
