Took a chance on this as a suit minus size markings. Fits somewhere between a 50 and 52 (similar to a 52 Dainese), on me at 175lbs / 41.5" chest / 5'10" it's a pretty race fit but I can get a spidi Warrior back protector on (and maybe slip their chest protector in too). I think those huge lateral stretch panels are doing some good work. Good shape, some of the decals have worn off a bit, and one area of the left slider velcro has been worn away. comes with a pair of unused RS Taichi sliders, and I have a set of Spidi's newest on order as well. I gave it a full deep clean & condition (it was disgusting when I got it), bought a new liner for it that has the 3d mesh at the back, so it's nice and supple and fresh. I just bought those Aero Pros here that fit me a bit more comfort like for street riding. $525 shipped from Woodbridge VA.
