This is a great pair of mountain bike shorts, I got a chance to ride in them all last summer and have been really pleased with them. The fit is awesome, not too xc, not too baggy - hits just a touch above the knee and is loose enough to be comfortable, but slim enough to stay out of the way on long rides. The fabric of the outer short is a super nice stretch nylon that holds up well and has some good stretch to it. But the inner short is what really sets this short apart from others -- the chamois is the best I've seen in a pair of baggies, and the liner fits well and stays cool with lighter mesh panels incorporated.
Been waiting years for Patagonia to offer bike short, and couldn't be more psyched with what we've got here!
