I wear MX style knee pads all the time, off-road and on-road. http://www.cyclegear.com/BILT-Kids-Charger-Off-Road-Knee-Guards The BILT look identical to to the EVS brand. I have both. I have the KLIM Traverse pants. I wouldn't trust any knee armor in them as I think the armor would move around to much due to the loose cut. And I also think the KLIM knee armor is too small. I wear a KLIM short under the Traverse. http://www.revzilla.com/snow/klim-tactical-shorts I don't own a BL Pro. Want one, just haven't been able to pull the trigger yet. I'd trust the armor in the jacket for what I would use the jacket for, ADV/Touring. I don't have any interest in the BL pants myself.
