Michael Rothwrote a review of POC Joint VPD Air Knee Pads on March 24, 2017
Familiarity: I've used it several times
I like these pads. I am 5'6 and 130 and a medium fits me the best. Small was WAY too tight even though I'm pretty sure I measured correctly! These are comfy for about 3 or 4 hours of XC riding and after that as I imagine any pad would, start to rub a bit. I have fallen a few times and they have protected my knee cap well. The side of the pad doesn't have as much padding perhaps to make them more flexible. I would recommend buying these. They are my first pair of knee pads, though, so better pads could exist. I certainly will try a different pair in the future with a bit more padding.
