My wife got me a pair of these for Christmas and I just barely got a chance to roll in them today. The first thing that impressed me is that she ordered me a size 34 and that is what I got. These fit me perfectly at the waist and they have a lot of room for adjustment. The velcro in the fly and on the waist cinch is really strong. I have pretty big thighs and these shorts give me plenty of room to move however I want.
I don't need or want to be worrying about my grappling shorts ripping or being pulled off of me while I am rolling. This is why, before these, I wore gi pants on no-gi days about 90% of the time. I like to feel confident in my gear and I feel pretty confident in these shorts.
If you want the official rundown, click on the link above and you will get all of the technical info about the material being staph resistant and all of that. The pocket on these shorts is actually on the hip and not in back like the description states but that doesn't bother me because I will hardly ever use the pocket.
