them Guarantee

Created in collaboration with Colombian illustrator Juan Villamil, Slitherin depicts the elusive Ruby Belly Black snake.

Deep in the Daintree Rainforest, amidst leaves that whispered secrets of ancient times, slithered Seraphina. Her scales, glistening like a mosaic of pink diamonds, cast a mesmerising spell on all who glimpsed her. With eyes radiating like molten gold, she is a beacon for wandering souls, guiding them through the dark towards dawn's first light.
  • Ultra soft pin-hole BottleBlendĀ® fabric
  • Made from up to five plastic bottles
  • SanitizedĀ® bacteria and odour control
  • 4cm band with plush inner microfleece
  • Lightweight 160 gsm for versatility and comfort
  • 88% Recycled Poly
  • 12% Spandex
  • Tagless with printed care label
  • Made ethically and sustainably in China
  • THE STYLE: This best-selling style is the perfect all-rounder!

    Created from BottleBlendā„¢, our very own recycled material, containing up to five plastic bottles. Flatlock seams for comfort and an inseam length of 15cm to reduce ride-up and eliminate cheeky chafe.
  • THE FIT: Each of our undies are made to a global standard. They are true-to-size, so order whatever size you would typically order for shorts. See our size guide.
  • THE MODEL: ${ chosen_product_model_description }

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.
