Stain on collar
I was disappointed to see this stain on the collar. The fit is great & feels heavy & well made. Not sure why it would be packaged with a stain on it & since it’s white it’s even more noticeable

Material and stitching so it doesn't look cheap.
Good quality for the price. Not wool. It meets my needs. I don't wear sweaters that often so buying a pricey one makes no sense. These look great when they are new.

Excellent quality - great buy! Looks sharp!
Size: Large, Color: Gray, Size: Large, Color: Gray
Great quality - this is a medium weight coat. Perfect as a car coat but too thin for cold winter days if you had to be outside for long periods of time. The fit is just perfect. Purchased a size large for a man 5’6 175 lbs with a small belly so peacoat double breasted look - looks great! Lining is standard and the grey color is very appealing. This is soft feeling coat made to look like wool without the heavy rougher wool feel. Only issue is that the coat comes packaged in a small bag and so when you open it the coat it totally wrinkled. You can knock out the wrinkles in the dryer with a wrinkle release dryer sheet or use a garment steamer but honestly the dryer trick is the key.

Long enough sleeves for a tall guy
Size: Large, Color: Green
I’m 6’3” and skinny, and was very impressed to find the sleeves were long enough for me in a large! The overall fit of the coat is boxy or straight, while I would have preferred a slimmer cut, I’m just so happy that the sleeves fit! The liner is nice, interior breast pockets on both sides are super convenient, and I love the green.
