Some of our most commonly asked questions

I'm the nervous type. Can I try a pair first?

Of course! You can purchase single pairs of previous designs (or special editions) in our online store for $30. Or, you can simply join the club for only $25 and cancel after your first pair if it’s not for you. That way you're guaranteed the new design!

Can I choose the design?

Nope! The Undie Club is built on the experience of a surprise. Not knowing what the design is you’re going to receive is half the fun! If you’re not a fan of surprises, you may prefer to take a look for the designs you like in our online store.

What’s the material?

All underwear uses our stupendously soft HyperMesh which is a blend of poly and spandex. It breathes to keep you cool and fresh, reducing ride-up and eliminating cheeky chaffe. The men’s are lined with HyperChill and women’s have organically grown bamboo.

Where are they packaged and dispatched?

Each Knobby is hand prepared, packaged and dispatched from our new facility on the Sunshine Coast in Queensland, Australia.

I love discount codes! Do you have any?

You cheeky bugger. But we bloody like it! Use code IMCHEEKY for a sneaky $5 off your first month. But, promise to keep that one to yourself.

What if I tell all my friends?

Firstly, we love you and good on you for having friends! Secondly, we have an epic referral program where you’ll receive a unique referral code to pass onto your friends that’ll give them a $5 discount and a $5 credit to your account!

Do you sell them in stores?

No way! Knobbys are exclusively sold right here on our website. It allows us to control and remain accountable that you receive a brilliant experience every single order.

Can I get them sent every second or third month?

Sure can! When you first join the club, you’ll be given the option to choose either every first, second, third or fourth month!

What’s your cancellation policy?

Super simple! You can cancel your account at any time prior to your next renewal. We hate to see anyone go (you especially), so please let us know if you are having issues and we will do our best to help.

Our mission is to be the most sustainable underwear brand in the world.

As one of the first Australian brands to adopt compostable packaging in 2017, we’re striving to eliminate all plastic by June 2022.

Each pair will arrive in a sealed paper based pouch and protective bag made from cornstarch, which is 100% biodegradable and GMO free!

All our papers and cardboards are recycled and carbon offset, because we give a shit.

Your goods are of such high quality that my first pair look exactly the same as the last pair you sent... so I have a drawer of underpants and it’s getting difficult to close.
