    It's like a party in your pants. Only louder!

      Pin-hole breathability
      Our innovative pin-hole mesh fabric incorporates a blend of Poly and Spandex. It breathes to keep you cool and fresh, reducing ride-up and eliminating cheeky chaffe. Ultra light and stupendously soft!

      Odour and freshness
      The integrated Sanitized® hygiene function from Switzerland protects against bacteria and odour. The high-tech wizz-bang protective finish prevents staining without affecting the softness!

    • BAMBOO
      Organic Goodness
      Our FSC certified and organically grown bamboo lining is naturally moisture wicking and resistant to pesky odours. Your glorious bod will feel cooler and more comfy than a cuddly cushion!
