All the wet suits and dry suits in my house are lovingly cared for in my dining room! Mostly hanging over the backs of chairs or on clothes dryers!
As the wife of an obsessive scuba diver, I don't think they have to be stored hanging if it's difficult, but I do know where ever you do put them, they shoudn't be subjected to major temperature changes. So not in the loft, in the suitcases!
dh soaks in cold water then rinses well with cold water. dry almost lying flat on an airer. when dry it's stored lying flat between 2 large cotton towels in a binbag on top of the wardrobe. it's important at it doesn't touch plastic and doesn't get direct sunlight.
Afraid so! It doesn't bother me. The house is big enough for the dining room not to be needed very often and when it is, he removes it all!
The diving dining room also houses the rest of the equipment needed for scuba diving. And that would be training at the swimming pool kit, open water summer kit and open water winter kit! Oh and DD does it too, so there's all of hers too!
