It took a couple of tries to get the sizing down. The sizing guide was actually confusing, but the exchange process was pretty painless. Once I got the correct sizing down, not a lot of complaints from me. I actually bought two of the pants(black and jean colored). The pants fit great around the thighs and calves. It’s not too tights and not too loose. Even with the knee pads, the stretchy fabric provides enough flexibility for free movement. The pants only do have one length. (The knee pads are still covering the correct area) With that said, my pants are a little too long, as I’m only 5’7. I just folds it a couple of times and it’s good to go. I don’t need to fold it when I’m wearing my Astars SMX-1 boot. As far as the durability, hopefully I will never have to find out.
