Omer Neoprene Valve Liquid Out Standard
A novel product
Looked at these and thought what a wonderful idea , I have pee valve on my drysuit, so why not on my wetsuit aswell. Problem is, its kinda obvious, its good for beavertail suits where you could cut a hole in your long john and cover it up with the tail. Its not very big, designed for the flaccid, and or under - endowed, child size. Bottom line, its for children, not adults, They just need to make a bigger one!
Quite small, but can be stretched for example by putting it over a botle for a day or so.
