I bought a pair of these for my vacation to Aruba along with another brand. I noticed on the initial try-on they were tighter in the seat and crotch compared to the other brand and my old trunks. I believed that it might just be something that would loosen up. Well, I played volleyball every day of vacation in all three trunks. The first that I played with these, while extending, I was....err... heavily exposed due to a massive tear. These may run a little smaller or the quality may not be as good as others.
