The fabric breaths really well and I can ride i these when its shorts weather. They're also very stretchy so there's lots of freedom to move. Fit is fine without knee pads, but ultra snug when I have my Fox Enduro Pro knee pads on. Durability wise, there isn't any. The light weight and breathability of these pants cone with a price. I buzzed my ass off a jump just once and burned a hole right through the fabric. I've owned many pants before and I've never burned through any of them. I still love them though.
