Our take on the AussieBum Men's WJ Wonderjock Swim Brief

The AussieBum WJ Wonderjock is a men's swim brief built around the brand's Wonderjock pouch, which lifts and supports for a fuller front profile. It is made from a modal and spandex blend, so it stretches and dries reasonably fast for pool and beach use. The best new price is $15.00 at Poshmark as of November 4, 2026, with three stores listing it new.
