i've been using a pair of these for almost a year now mostly for downhill mtbiking. i've also use them on my fixed gear this winter. thet are very thick . i think they feel better on smaller diameter grips/bars.lots of padding on the palm . definitly helps absorb shock. kevlar knuckles are cool but maybe a little overkill. the wrist strap is starting to rip but a few stitches stopped it from going further. i've crashed a few times on dirt and they are holding up pretty well.
