On ordering this I was half expecting some really thin material with a pattern printed on. So it was a pleasant surprise to discover decent material - 98% cotton - with a woven pattern. It is not particularly heavy but thicker and softer than many quality shirts I've bought from name stores, and I expect it to last well and be easily ironed. Close inspection shows the seams firmly stitched with no loose ends, and the button holes are a tight fit (so buttons aren't going to pop out unexpectedly).
Similarly, mail-order clothes often seem sized to fit something almost, but not quite, humanoid. I am a 41" chest so tend to fall between the 38-40 and 42-44 sizes. A roughly 30" waist usually demands a 'slim fit' or 'fitted' style, and arms half an inch short of being 'gorilla-like' warrant a long sleeve. Given those constraints, a medium size seemed a likely contender, and when it arrived it was an almost perfect fit - a bit roomy in the stomach area, which is normal for 'regular' fit but wasn't as bad as some. I expect it will improve after a wash or two, too.
A small point: the product blurb mentions 'button down' which usually means the collar. It is not of that sort - the photos are realistic representations of the product. At time of writing, the photo that's shown when the dark blue shirt is selected is of the red shirt. I had a slight ordering hitch where Amazon appear to have cocked up which shirt is really ordered, but the vendor was very quick to sort this out once informed.
