Stylish, packable warmth layer I'm using for travel the fits and looks great!
Size: Large, Color: Gray, Size: Large, Color: Gray
I like the COOFANDY brand a lot for good looking clothes, that fit me correctly (Large size, for me 180lbs 6'0", athletic build), all at a reasonable price. This Jacket fits me great and looks great, and it's stylish enough that I'll feel comfortable going to museums and restaraunts, etc while we're away in Europe this fall. I bought the gray which looked correct vs images on the web, and a good color in my opinion. My pictures were done in different lighting because of needing to be in front of the mirror, but color is accurate on web. I like having the hood, which will be good for outdoor travel / walking in sometimes rainy weather, and hood looks good down (not too bulky). Zippers seem good quality, and I like zippered pockets, plus there's internal pockets (not zippered) if you desire, and an included stash back for compact packing into my day pack. Sleeve cuffs and right size and nice. Note, that there is no bottom waistline drawstring adjustment, but I don't need such because it fits me great and I wanted something more city and less outdoorsy. Really like this jacket for my need, outer layer for city type travel while staying warm and looking good.

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.
