Hands down... the best knee pads on the market when for looking at the comfort and protection factors. Realize it doesn't get the full shin coverage that many other leg armor options, but that is what helps make is so comfortable.
I wore them dirt jumping the other evening and had a couple bails as well as taking a pedal bash right on the kneecap and barely felt it. As well, I was driving hom in my car for 20 minutes before I realized I still had them on!
My only complaint is the cost. The Kyle Strait models seem similar and are half the cost. I haven't tried them so I can't compare, but I already own the Evos and am stoked so no need to experiment.
