Got my boy a 5/4 O'Neill with zip on/removable hood. Very stretchy and very warm. No back zip and very warm. He loved it. Much better than my older O'Neill with less stretch and the back zip. Never TOO much rubber in the winter.
I just got my HyperFlex 5/4/3 Flow from wetsuit world in Stone Harbor. It was 216. 68 after a 10% coupon I got off there website. It has great strech and there cut fits me very well. I will post up some pics of it and do a product review as well for all who are interested . Dont let the price of the lear you away. They are a very well made suit the quailty and customer service is awsome
