Very durable and very appealing
Grandson loves his jacket. Said it keeps him warm and isn't bulky or heavy.

Good for the price but not as roomy as a North Face.
Size: X-Large, Color: Black
The jacket is lightweight and warm. It isn’t as roomy as a North Face puffer jacket but fits me fine (6’1, 190). I find that when I zipper it to the top, it irritates my throat area a little. The color is what showed in the picture.

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.
