after using surf suits wetsuits semi dry suits and dry suits. Open cell is by far the best IMO.
also after struggling with girlfriends trying to get in and out of semi dry suits/ wet suits lube them up and there is no tears.!
there is somthing called Immersion Diuresis
http://en.wikipedia.org/wiki/Immersion_diuresisthat causes the body to piss its self from being weightless.
there are 2 types of people that wear exposure suits
1-those that piss in them
2-those that lie about it
there is a trick if you cut the bib off the long johns you can pull them down like pants and piss and shit till your hearts content.
happy days
