I gave the jacket to my daughter, but I do recall it is very generous in the hip area.
My only advise to you is, google the company Trespass, ask their customer service department if they have the specs on this jacket.
I have always done this in the past when I need to know more info on a specific measurement for a garment. They will gladly help
you with all your questions because they are helping a future customer, even though you are buying it from somewhere else.
I hope this helps you.
I don't have a number, but it seems very adequate to me. This jacket isn't a long one and the bottom comes right at the hips. There is a cinch cord you could tighten, but I never fool with that. Sorry to be so imprecise.
i beleive, it is 53-54 inches flat. should be half that zipped and untoggled, hope that helps, after all i am a mountain man. lolol
