How It Works

We've got your back (and your pits)

Underarm protection: We catch moisture before it reaches your outer shirt. But this is only half the problem.

Upper-back protection: Apparently every other undershirt in Australia forgot you sweat here, too. And this is the spot that everyone else can see except you.

So I just...wear it?

Yep. Just put it on like any other undershirt. Then go about your business.

Walk into the meeting without the bathroom check. Put your arm around your girl without worrying you'll gross her out.


No more wondering if you've left a damp mark on the back of your chair. No more wiping down with paper towels or sneaky blasts under the hand dryer.

You’ll pay more for our undershirts. But you’re paying to finally solve the problem.
