CTi2 Vapor. If you can get a prescription, it only costs your deductible depending on your insurance company. Just going and getting one made costs $850. I use the Vapor and for a knee brace, it's really good. It's not too restrictive and is very light. Plus after having ACL reconstruction and 9 months of rehab, I like having the added confidence that my knee brace gives me. I think mine is more of a mental thing now, as I made sure my injured knee and leg were at 100% strength before even getting on a board again. No brace will prevent all injuries and nothing beats strong and flexible legs, but I like the Vapor.
