I bought this jacket in a "Large".  At 5'-6"tall, and 155 lbs. I'm not exactly a Large man.
Much to my surprise, the fit was very good. The nylon lined, insulated sleeves are a perfect length for me.  The body of this coat, is nicely lined with synthetic fleece, that is bonded to the shell.  This makes it wind resistant and warm, and ample enough to wear a heavy vest under
it.
I loved this jacket so much, that I bought another one.  This time I got a medium size, hoping for a slimmer fit for spring. .The sleeves are slightly short, and the cuffs are rather tight. It still works for me.

This jacket is very light, warm, water-resistant, wrinkle free, Quick drying, good looking,
inexpensive, and practical. I give it a Big Thumbs Up
