I had a set of these in the yellow, and wore them for a ride or two... they were the most uncomfortable pads I've ever tried!! It might be because my knees are rather knobby, or it my be due to the design... either way, I went out and purchased myself a nice set of 661 EVO knee pads, and have never looked back. And I wear them for XC/trail riding. The G-Form pads are exactly the same on the back/inside as it looks on the outside. Only a thin layer of spandex seperates the pads from your kneecap. G-Form did a great job in designing the pad for coverage, but I feel that they need to go back to the drawing board and rethink the design of the backside/inside to provide better comfort for the wearer.
