in our local speedo shop, they have one of them suits on display. The sales woman told me some local aces have tried it on (it's true - even an XL suit on an S person takes 15+ minutes to put on) and swimming (they said they felt like a plastic soda bottle in the water).

It's a really weird fabric - lycra but tough and very little stretch.

It's not that I think I'd have any use for it but it was cool to see it, like a space suit.
