I am very impressed with this vest. I am 6'4" tall and weigh around 195, so I am pretty tall and slim. I generally fit right between a medium-tall and a large-tall with my chest measuring around 43 and my waist at 34. Because I am sort of between two sizes, I often have to vary between manufacturers which size I get. I ordered this vest with some hesitation because for whatever reason vests seem to have large variation in sizing. The large-tall fit me perfectly. It has a small amount of wiggle room, but not so much that I get a draft up my back. I usually wear a vest with only a long sleeve button up "dress style" shirt or a light flannel and this works perfect for that. A thicker undershirt like a hoodie or a sweatshirt would be pretty tight.The fleece lining in the body of the vest is the shorter/denser style which is much more comfortable to me that the longer style that I usually see on vests like Carhartt. The outer pockets are lined with a light fleece that makes them very warm and comfortable. The neck area is also lined with this light fleece which is much more comfortable than many of the unlined necks in other vests. Pocketing arrangement is simple and effective with two "hand" pockets, a left chest pocket, and a pocket on each of the interior sides. I can't speak overall to the durability because I only just received it, but the construction looks solid with clean double stitching at most edges. It is clear that the manufacturer of this vest thought about many of the small items that make it more comfortable and user friendly while still being durable and clean looking. The cost is reasonable comparted to other manufacturers. Very impressed.
