From the release:

Leo Burnett creative director, Michelle Walsh: “Every bloke gets hot, sweaty balls (so I’m told) but they’ll rarely talk about it, let alone do something about it.

“So, this was a fun, playful way of getting them to consider how they treat their precious cargo and prove to them that the right jocks can make all the difference.”
