These shorts are very comfortable. I've used them on several 3 to 4 hour xc and all mountain rides with some road or xc style shorts underneath. They didn't get to hot. I wear padded compression shorts under them for some rougher rides and they work great. The shorts work well with knee pads. They're very durable had some sliding crashes with them on and they've held up just fine. I have not been able to use these shorts at a bike park for some serious all day dh, because the parks haven't opened yet. I have high hopes they will succeed the demanding riding I will be doing when they do open.The Gravity shorts are comfortable durable and look badass!!! Highly recommend.
