The lighted board thread got me thinking about some of the really stupid surf products I've seen in my 30 years of surfing. Those include:

webbed gloves
the 'turbo tunnel' fin
surf sunglasses (aka oakley waterjackets)
lyca surf shorts (I'm talking about the cycling style shorts of the late 80s)
ultra short boardshorts
front foot traction pads
go pros

Did I miss anything? (I'm sure there is some really wild stuff from the 60s and 70s.
