I'm 5'6; 145lbs and usually wear an A1F in Shoyoroll sizing. A1S seemed to be the clear analog in Hyperfly sizing, so I ordered this gi in that size.

Ordered, received promptly a few days later, and this gi is ginormous. It's probably closer to an A1L/A2 cut in other sizes. There is way more excess material on this than is possible to shrink in some warm wash-hot dry cycles. Otherwise, it is constructed of the material and quality that I expected for this price. I am returning it of course, but would need to do some research as to what the appropriate size would be for this model since this model seems to break the mold. For prospective shoppers, DEFINITELY SIZE DOWN 1-1.5 sizes.
