I love swimming laps and splashing at the beach with my family. I also swim in heavily chlorinated indoor pools all winter. I have several Arena briefs in both PBT material as well as regular poly spandex. I mostly save the PBT's for the indoor chloriine situations. Of the PBT Arena briefs I've tried, this is the tightest fit by far. They are almost spray painted on but amazingly comfortable. All of my other size 34 Arena's fit just a tad more loosely. However, these go on fine and stay put no matter which waves I tackle- they're coming to the beach! They look and feel great and I feel like a better swimmer when wearing them. Excellent and tough stitching, fit and finish throughout. These will last a long time. They are pricey but well worth it. I may purchase another one in "painted red" or "orange". The even quality of this print is good and practical for this type of suit- fun, functional but not too revealing. Keep making the sides this thin, Arena. Two and a half inches on the sides is more than enough for most of us.
