    Aussie Aussie Aussie!

    This pair is so fun, not just for the olympics but the rugby that came to Australia too! Repping that green and gold is so much fun.

    Only have a few.

    I can't rate these high enough, I have worn Knobby underwear for years .

    but now my 4 year old son asks every week when is his new knobbys coming.

    The Hex appeal are his favourite to date, loves the glow in the dark.
