Personally, I hate hoods. If I was ever to have to wear one though, then this one by Quiksilver would be my choice.  The polypropylene vest is thin and adds another layer of warmth to my core region which is always needed anyway.  The hood is 2mm thick so not too restricting and it creates a really nice seal between my wetsuit and the hood with the vest and the extra flap of neoprene that acts like a seal (sic).
