Great while riding


I've had these for three years now, and they provide great protection during minor crashes (although I think knee braces are a lot better overall). They are comfortable when riding, and I never notice them once I'm on the track. However, they are terrible for walking around the pits, sitting in bleachers, etc. I give four stars four their use as a knee guard while on the bike. If you don't take off your pants between motos, they would get 2.5 or three stars, because they are quite uncomfortable when you're off the bike. They are superior to run-of-the-mill knee guards, but quite inferior to a decent knee brace. And they're pricey for what they offer, but mine have held up well so far. I would recommend these if you really need to upgrade knee guards, but are not in a position to afford braces. Otherwise, just get some Asterisks and be happy.

Not so Impact resistant after all


Knee guard has cracked on the lower part of the knee cup from a minor fall.One of the buttons on the same knee guard has separated from the padding




Great protection


Great protection but they have no padding for the straps and they tend to slide down into my boots."
