Not very puffy puffy jacket
Size: XX-Large, Color: Denim Blue
At xxl the shoulders fit well and perhaps the first jacket where the sleeves came down to my wrists and not halfway to my elbows if I reached forward. Love the zipper. The zipper pull is at my right hand side. It is where i would use my right hand to engage and pull it closed. The zipper glides smoothly. The hood is voluminous. There is no string available to control the fit of the hood. As it us the hood is much too large. It makes the jacket look cheap and unfinished. The jacket would be immeasura bly better if the was a bit more fill in the body and a string pull in the face of the hood to bring the fit closer.

It's thin but it's good for cooler mornings and windy days
This jacket is not super thick or sherpa/fleece lined. But it's great for cooler temperatures, windy days, or staying warm while out on a boat. It's lightweight, cuts the wind and is great for layering. Folding it into the bag makes it ideal for travel and camping

Okay for the price
Size: XX-Large, Color: Denim Blue
The product was light and compact for packing for an Alaska cruise. It was also sufficiently warm and relatively rain resistant. But on the second day of wearing, the zipper blew out. I was able to fix for a short while, but in the end, I couldn’t use it.

Great deal on a shacket
Color: Khaki, Size: X-Large
The shacket looks like it is depicted in pictures. It is oversized in general since it is intended to be an over garment. The weight of the cotton is heavier than a normal cotton shirt, but not as heavy as a denim jacket.
I am 5'8" tall and 175 pounds. My sport coat chest measurement is 44 inches. I ordered XL so it would be large enough to cover a T shirt and shoulder holster for S&W Shield to CCW. I washed in cold and hung dried, and it still feels a little too large. I will try to wash and machine dry and see if the fit improved.
The shacket looks to be worn with sleeves extended. I tried rolling up the sleeves and was only able to get two rolls. A third roll was not possible because it wouldn't fit around my forearms even though I'm not muscular. Those wanting to roll up their sleeves may need to alter the shacket.
I was pleasantly surprised that the shacket did not have a chemical smell, which makes sense because it is 100% cotton. It instead smelled like cotton.
After the first wash I didn't notice any imperfections. The buttons don't seem to be unraveling, and the other stitching looks to be holding. The shacket comes with one extra button.
Overall, it looks like a nice shacket. Because it comes from China, I was expecting a stinky, plastic shirt notwithstanding the advertising. But no, it looks like it's all cotton, all quite clean and healthy.
For the price, it looks like a great deal. Note that they can't fit all body types. If you're muscular with large arms and shoulders, I would expect the usual difficulty in finding a fit.

Good quality, runs small through middle
Color: Nave Blue, Size: 3X-Large
Good looking shirt and much thicker and sturdier than I expected. Run small in gut though. I'm a 3X in everything but had to get 4X in this.
