What’s the difference between a Unisex cut and a sex specific cut?

Uhm,

Difference between mens and womans can be wheter the zipper pull is on the left or the right, but this also varies on the country you're in.

Than if you look at the difference in build between a man and a woman. The ratio between the circumference of the hip and the waist for men is 90% and for women 70%. Womens clothing is usualy cut too slim in the waiste for most men. My guess is the unisex is more cut to a mens waiste than a womens waist, but this is just a guess.

Unisex is cut for men — and women would choose one size smaller. Most times, for shell jackets, etc. that are meant to be worn a bit larger (to allow for layering underneath) — gender specific is not so important as just getting the size reasonably close.

For closer-fitting garments, gender specificity becomes more important.

MontBell's new outerwear products sometimes debut as "unisex" (i.e. men's version). If later followed by a women's version, then the formerly unisex will be re-labeled as "men".

Thanks Benjamin! That is very helpful since I plan on wearing the thermawrap parka with a vest or fleece underneath I guess I don't have to worry as much.
