Camwrote a review of POC Joint VPD Knee Protectors on September 15, 2013
Familiarity: I've used it once or twice and have initial impressions
I have used this pads on just one 25 mile ride ride so far. Have yet to crash but the vpd works like magic when bending and punching the pad. Mine are a bit small but hoping they will stretch out a bit. On the ride I did 3000 ft of climbing all with the pads on. Great flex and did not feel overheated.
