Not for anyone taller then 6”1
Color: Dark Blue, Size: 3X-Large
It was a great quality sweatshirt! I did end up returning it only due to the fact it was to short for my husband who’s 6”8. Other than that we both loved the color, comfort, and wearability! Plus the price was amazing.

Thumbs up on this one
Color: Khaki, Size: X-Large
Very nice soft material that seems like it will be easy to clean and pack without wrinkling. A bit heavier for cooler mornings and so nice it has pockets. Nice pullover.
