As a man who has to go through the awkward task of trying to fit these rental wetsuits designed presumably by men for curvy women, I know precisely what one of those issues can be.
I seriously do not like trying to fit a woman into some of the suits. The worst ones are the woman who look like woman (in other words they have HIPS to pull this 7mm monstrosity over) and young girls who are just starting to develop their hips and often have to be fitted into suits for small men. They always understanding but I always feel like something less than a gentleman when this happens.
When women start to design some of this 7mm suits for the rental fleet instead of men, I will know that there is one less "women's only" issue.
Also, I went through an Open Water class with nothing but young ladies. Trust me, there are many issues specific to women that men never dream of. I ,for one, am happy that there is such a forum.
