Ksubi (formerly known as Tsubi) is an Australian fashion label, co-founded and directed by surfers Dan Single and George Gorrow.

The brand is known as one of the most notorious, distinct, street-wise and innovative fashion labels in the world, with a diverse range of fans ranging from Australian underground musicians and New York City hipsters, to celebrities and fashion icons such as Aaron North, Kanye West, Gemma Ward, Mary-Kate Olsen, Pete Doherty, Madonna, Cory Kennedy, Kate Moss and many more.

And as for the sunglasses? They're worth talking about too: just cool and covetable.

Iris Optical has carried Ksubi sunglasses since April 2007.
