The sensational AussieBum Wonderjock, a range of men's swimwear from Australia designed to "lift and promote", has already sold more than 250,000 pairs. “Size really does matter to the modern man, and I think swimwear is where this technology is really needed,’’ aussieBum founder Sean Ashby explained. “When you walk out of cold water, everything gets sucked up into no-man’sland. This makes the most of what’s still there.’’ Wonderjocks became available on aussieBum’s website only last week, but more than 2000 pairs a day are already being sold - at AUD$32.95 each. “Basically, the Wonderjock does for men what the Wonderbra does for women: it lifts and promotes.’’ Wonderjock underwear has been an international success story since its launch in November last year and has been snapped up by stars including Ewan McGregor. “We found out Ewan was buying them only because he made such a huge order and we had to do a credit check,’’ Mr Ashby said.
