Floating shell concept: hard outside shell is kept away from your elbow as it rides on a flexible membrane on the outside layer. TPR rubber limiters keep the cup where you need it even during extreme crashes.Sold as a pair.
"These are very comfortable elbow guards, but they tend to slip down your arms after landing a jump. Additionally, they are a little soft as far as the rubber protection. The pro on these guards is that they are far more comfortaable than any others I have tried. Cons - slip down arm, impact protection was a little soft."
