The Artwork

Nelson Gibbons
Sunny Boy is just your regular happy Sun. Taking a day off from being the source of all life for a day to relax and enjoy the simple things. He likes to walk his sausage dog, go for a dip, play the banjo, he can even do a kickflip. Join Sunny Boy and enjoy the simple things too in this relaxing shirt.

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!
