Keep calm and pull these on. Whether you’re a Brit abroad, an England football tragic or just partial to a proper pint, this one’s got your name written all over it. A proper celebration of British icons, Keep Calm and Carry On serves up a full English of colour, character, and cheeky charm.

This design is part of the Around the World collection by Sydney artist Sindy Sinn. Known for creating bold, loud, unapologetic artwork that makes you say “fuck yeah!” at first glance, Sindy’s creative fingerprints can be found everywhere from Metallica and Blink-182 to UFC, Spotify, Jameson and Liquid Death. Fresh off a 2026 Archibald Prize nomination, he’s brought his signature energy to Knobby’s latest passport-worthy collection.

Got Some Questions?

Of course! You can purchase single pairs of previous designs (or special editions) in our online store. Or, you can simply join the club for only $29 and cancel after your first pair if it's not for you. We also have a Love them Guarantee which means we will refund your first pair if you don't love them.

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.

We offer underwear created from a range of materials including BottleBlend™ (our very own recycled & sustainable material), TENCEL (a 100% traceable fabric derived from wood), bamboo and merino wool.

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

You can shop the full range online, and you'll now find Knobby in-store at selected retail locations too. See our locations page.

Absolutely! We ship Knobby customers located all around the world including New Zealand, USA, Canada, UK, Hong Kong, Switzerland, Turkey, Iceland, Monaco, Norway and more! For more info, see our shipping page here: knobby.com.au/pages/delivery

All Knobbys are only $29/month and shipped free Australia wide. Simply select your size and you'll receive a new pair every month. Soon after, your first Knobby will arrive at your doorstep, beautifully packaged with your snazzy welcome pack! Your subscription will renew on the 7th of each month and you can cancel anytime!

No bloody way. We don't have a fee, no fine print, you just pay for your underwear each month. We know you like things pretty simple, that's why we've made the most upfront transparent system with no hidden fees.

The Undie Club runs on a single monthly cycle, with one fresh pair delivered every month, billed on the 7th. Everyone gets each new design together.
