not as good as others I've tried

I bought these because they look a lot like the kind target used to carry.The ones I was hoping to replace are smooth and light, yet strong. They work as swimsuits, if you don't want one of today's bulky saggy soggy neon beasts covering half your body when you swim. The only downside to the target ones is that the elastic ages pretty quickly from all the (chlorinated) water.These were more expensive and slightly longer, but swimming in silk still beats most other materials, so I gave it a try.They aren't as comfortable, as briefs. They do move around and get stuck more than they should. The elastic, while nicely stronger than the target ones, feels slightly too industrial to me. The fly is, for whatever reason, too easy to, shall we say, accidentally bypass.And I know they aren't made for swimming, but I do want to add that the fabric seems to be aging VERY quickly - after only half a dozen uses, it feels thinner and stiffer than it did.
