This is a beautiful coat,  not too thick,  removeable bib, double breasted with a single inner big button at the inside flap and big buttons at the front. It is surprisingly warm for such a medium thickness coat.
However, sizing is a problem with this coat; here's my info:

I'm 5'9", 200lbs. But once I got the XL size coat I soon found out that for this coat in particular, chest size is the most important. The XL was too tight around my shoulders and upper back and I literally could not do a hugging motion, it felt as if the coat could rip. My chest measures 47" (chest alone) and 53" ( arms included). The sizing info provided in this coat's page is NOT for this specific coat, so don't base your purchase on it. Do the following:

Measure your chest in two ways:
1. Raise your arms and measure around your chest at its thickest section.
2. Lower your arms and measure around your chest,  at the same level as before, but this time including your arms (a bit bellow the shoulders); this measurement shouldn't be more than 10" greater than the measurement from step 1; if it is,  go a size larger.

Hope this helps.
