Well, thanks for your answer...
It's a pity that the company you work with cannot get a thinner neoprene... I have seen to many surf equipment, jackets, etc.. that use a 1mm. neoprene... which I think would be more than perfect for Zam Wesell...
Constructed from 1mm G-Rex Neoprene with a durable outer nylon coating.
That is a 2 coat, VERY VERY THIN... and think that can be the "solution" or the way to look (well, if possible off course !!! ).
