Unknown Great Wave Rashguard


The Unknown Great Wave Rashguard draws its inspiration from the story of the "Great Wave" dating back to the early 19th century. A print by the artist Hokusai depicts the tale using rich colours and synthesising traditional styles with modern artistic perspectives.

This rashguard is constructed by hand, utilising Italian sublimated ink and premium spandex/polyester mix to ensure your comfort. Rapid dry and anti bobble technology place this rashguard on the cutting edge of rashguard technology. Vibrant colours and inspiring design make this one of the most exciting nogi sets on offer to date!

  • Italian sublimated ink for enhanced graphics
  • Premium spandex and polyester mix for maximum comfort
  • Unique Progress custom cut for the perfect fit
  • Breathable mesh side panels for improved ventilation
  • Rapid dry technology
  • Anti bobble technology
  • Triple flat lock stitching which will never rub and last for years

Although all our rashguards now have anti-bobble technology, we always reccommend washing your Progress rashguards on a cold wash. If you have to wash hot, please do not exceed 30 degree.

Do not use a tumble dryer, only hang dry, all our rashguards are quick drying so it will only take a couple of hours to be ready to roll again.

Never use bleach!
