Natural. Ethical. Sustainable.

Made from superfine 94% Merino Wool fibres grown in the foothills of the Great Dividing Range in Victoria, Australia. From country air to underwear, it’s cut, sewn and transformed into this pair at our Melbourne factory, then packaged and sent to you from our Sunshine Coast warehouse.

Merino wool reacts to changes in body temperature and helps you stay warm when the weather is cold and cool when it’s hot.

Created to support the Australian textile industry, it has been certified to carry the iconic Australian Made and Owned logo.

Cutie up your booty in the super stylish and oh so comfy High-Waisted Shortie with a higher waist and slightly longer leg. This versatile little beauty covers you, from loungeroom yoga to bedtime comfort!

The stretch of Merino Wool is much greater than BottleBlend and Bamboo, so you may need to go down a size from your current Knobby sizing. Refer to our size guide or chat with the support team.

Each pair of Knobbys will arrive in a custom designed, certified kraft paper package or a sealed paper pouch and postage bag made with cornstarch, which is 100% compostable!

All our Australian printed papers and cardboards are recyclable, FSC certified and made carbon neutral, because we give a shit.

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