Alpinestars Bionic Mx Knee Protectors 4.3 5 3 3
The only thing I have sent back to Revzilla. Two things made me send these back, I really wanted them to work out. 1. One of the supporting straps (very small) wasn't sewn in. It is like the person or machine just missed their mark. 2. You have to have tiny legs for these to fit! I have thick legs but not what I would call overly large. The straps plain didn't reach above or below the knee. Here are my measurements, if you are near mine stay away from buying these. 20'' Above the knee 18'' Below the knee They look cool, I don't know if the pads inside are CE approved. And the plastic felt mid grade leaning to cheap. Like they would be good for one real crash, but that is just me guessing. Felt kind of like a Honda Civic, nice but not going to WOW you, but would do the job. April 21, 2012
Great Product! These knee pads are very comfortable and they mimic natural knee movement. The varying side straps are adjustable and can be adjusted to whatever fit you would like. High satisfied with these knee pads! September 6, 2011
Perfect Awesome product for what they are. Don't let your knees to be exposed on long rides. I use these for anything more than just around the town riding (have a pair if Dainese V knee guards for city crusing which are slimmer) The protection and padding in these are second to none. They are very comfortable and protective (for what they're supposed to do), they're lightweight to the point u forget you have them on, very breathable even though they don't flow air enough to be 5* in that category, but they won't let your knees be sticky and sweaty. I have a lot of protective gear ('coz i sacrifice all the bike tuning and customizing in favor of protection) and Alpinestars, Dainese and Forcefield are simply the best (in no particular order, they compliment each other extremely well with every brand bringing something else to the table, f.i. Forcefield-THE BEST back protector, shirt and shorts, A* THE BEST protective vest and street knee guards, Dainese THE BEST protective leathers...) Everyone who is like me- that cares about protection a little more than the average Joe-should honestly pick these up. $100 is a lot less than a patella tendon surgery (trust me, unfortunately i know) These won't protect you from ACL/MCL injuries, as they don't have the lateral support needed for this kinda protection, but the braces that do are about $500 more so you have to be reasonable. Overall, i haven't find a better, more comfortable patella, knee cup protection, that you can wear under a bit looser riding pants, yet April 9, 2011
