Unlike other pads, G-Form PRO-X Knee Pads are flexible, lightweight, breathable, and machine-washable. Their fully articulated design offers maximum protection centering on and surrounding your joint, with virtually no bulk. With G-Form, you never have to worry about compromising movement – in fact, you won’t even realize you’re wearing them.
I hardly even know they're there even going uphill. Only had one chance to "use" them and they worked admirably to protect my knees. The rest of my body didn't hold up so well. Next up, elbow pads!
