Ready for a shamrockin' good time? Nothing brings Aussies closer to another nation than sharing common interests of our most loved things, beer! It's a spin on our fave adopted national celebration! These leprechaun larrikins will bring you the Luck O' The Irish!

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!

    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!
