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 oni 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.
