Frequently 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 $29. Or, you can simply join the club for only $25 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.

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?

Our underwear is created from BottleBlend™, our very own recycled & sustainable material. Our Men’s range is lined with HyperChill, a moisture wicking fabric and Sanitized® for bacteria and odour control. Our Women’s bottoms are also lined with organic bamboo.

Where are they packaged and dispatched?

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

Do you sell them in stores?

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.

I don't live in Australia, can I still join the club?

Absolutely! We ship to New Zealand, USA, Canada, UK, Hong Kong, Switzerland, Turkey, Iceland, Monaco, Norway. For more info, see our shipping page here:knobby.com.au/pages/delivery

How does Knobby Undie Club work?

All Knobbys are only $25/month and shipped free Australia wide. Simply select your size and if you want to receive a new pair every month or second month. Soon after, your first KNOBBY will arrive at your doorstep, beautifully packaged with your snazzy welcome pack! Your subscription will renew each month on the same date that you first subscribed and you can cancel anytime!

Is there a fee to join Knobby?

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 it the most upfront transparent system with no hidden fees.

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 monthly or every second month. You can even customise your plan to be every third or fourth month too by shooting an email to our support ninjas.
