Absurd proportions - Marmot Calen Jacket - Mens

I bought this on sale, and with an additional discount, because I think this type of jacket tends to be absurdly overpriced but wanted to try one one for bike camping. But of course anything on sale tends to have something wrong with it and so the game becomes one of selecting something whose shortcomings do not interfere with your needs. I had assumed that color was the primary reason this was on sale, but the issue was fit. As a cyclist, I am familiar with various degrees of athletic fit and tendencies within manufacturers. The fit for this item does not match the chart provided by Marmot via Camp Saver and is inconsistent through the garment. Shoulders and sleeves are within reason, but the neck has an unnecessary gap when zipped up, despite a fleece lining that would insulate nicely if less loose, and yet at the same time, the body is comically snug through the entire torso, off by a good two inches if not three, which among other things compromises its insulative capability through the core. By way of comparison, my son's similar coat by another manufacturer fits me far better and is a medium. I gave the jacket to my other son, who is a lithe 16, and it barely works for him. This was enough to get me thinking that my estimation of Marmot is inflated, but mainly I am annoyed that the size chart was inaccurate.
