A lot of people whom view this show particularly judge it as a piece of pure unadulterated trash, unfairly in my opinion. British game show networks are known for being original, and I thought the idea of nudists performing tasks based upon a popular children's game show at the time was a decent concept.
Essentially this was Channel 5's attempt to get more of the sleaze audience. This was "The Crystal Maze" for nudists - it had a series of activities (like a big assault course) that the contestants had to compete over - the twist being everyone was buck naked (save for helmets and safety straps etc).
This was a very funny game show with naturists as the contestants. There were 5 men and 5 women.
