I'll start by saying I HATE buying clothes online that I can't try on first, but this is exactly what I wanted at a reasonable price, so I went for it. With a measured 52" chest (6'2, 265 lbs), their fit chart said I should purchase the 4XL which meant the garment would have been 56" in diameter.At the risk of playing Amazon by telling myself, "self, if it doesn't fit, just return/exchange it", I stuck with my intuition and went with the size vest that was closest to my actual chest size, not the recommended "suitable for chest" size. As such, I ordered the 2XL. When it arrived, it fit PERFECT and EXACTLY how I wanted it to, with even a tad bit of room for a hoodie if I wanted to.All that said, the quality is pretty decent. I would have preferred a bit thicker 1.4-1.6 mm leather, but most of this is double layered 1.1-1.3 mm, to its good enough for me. The stitching is clean with no loose threads and several interior pockets for whatever.I would only change two things:1) I wish they had sewn a zipper in the lining across the back belt line for a seamstress to use for patches, but any decent seamstress should be able to work with what it is.2) I would have like to seen buckles on the sides at the belt line for cinching up; some of use have bigger shoulders and chests than we do waists.These are design issues though, not a problem with the garment and would have increased the costs. I LOVE this thing, and wouldn't hesitate buying another....but like I said, don't let the "suitable for chest" size screw with you. Get the size that lists the GARMENT SIZE closest to your actual measurement, or at the most one size larger...otherwise you'll be disappointed.
