Not worth buying
Size: Small, Color: Light Blue
Cheap material, stitching looks cheap, and the collar is way too big, almost like it’s a wrong cut. It doesn’t look good at all. Decide it to throw away in the trash right away. It’s a $25 mistake.

Pullover is soft and comfortable. Too soon to comment on shrinkage but quality seems to be good. Not heavy duty but good quality.

FYI
Size: 3X-Large, Color: Khaki
Me and my wife liked the look of the sweatshirt. The color is what I expected. Shirt was comfortable. I got the 3X and it fit pretty good. However I was debating if the 2X would have been better, but I have big shoulders and it may have been tight. Length was pretty good, but my thoughts it could have been just a tad longer.
