I bought this expecting it to be a bathing suit ("water trunk"). When it arrived, I saw a label on it that suggests it it made to be worn when fishing (or boating, etc.). It has belt loops, another hint that it's not a pair of swimming trunks. Unfortunately, I've gone on vacation and taking this with me as my only swimming trunks, so I'm forced to use it. I like how quickly it dries when I get out of the ocean -- the water beads up on it and falls away, but it's not as snug around my waist as I'd like. It does have an elasticized waistband, but not as strong or as wide as I'd like it. After this vacation, I'll probably just use them as camp or gym shorts and buy another bathing suit.
