Well-fitting performance jackets are hard to find - I am 5'1" with athletic biceps, wide hips and a big chest. This one gets close - I can open the bottom zipper for room for my hips and I can zip it over my breasts without warping the zipper. However, there is barely enough room for the width of my shoulders and my upper arms. I am able to walk/hike/drive in it but I couldn't put my suitcase in an over head bin or throw a football in it. I'd recommend this to those blessed with or work hard for boy-ish figures.
