Dont' know if this helps, but the new 5mm suit I bought is actually a half size smaller than my 3mm. The new suit is a super stretch material. I guess material and cut will make be the deciding factors.On that same topic of 3mm and 5mm, would you change your size when moving to a 5mm? i.e. order one size bigger..I just moved to the US and for the first time i will wear a 5mm suit. I used to have the cressi world comp 3.5mm which i loved because its warm and has metallite lining on the inside which helps you wear it with little hassle yet performs like an open cell in terms of warmth..so i ordered the same one in 5mm..got it last night...that thing is verrrrry thick compared to what im used to..im scared to put it on i might not be aable to take it off should i have ordered one size bigger? or is this just the normal "adaptation to change"
I try on so many suits in the shops before I find one that fits well, I don't know how you guys manage it buying online.
