Great weekender
Color: Beige, Size: 17 Inch
Great size for weekend travel. I love the look. Zippers are strong. Material is also strong. I've received many compliments on the bag. Easy to carry. Love that it has a side handle. I do miss that there are no side pockets, but great bag overall.

Doesn't Fit 16" Laptop
Color: C-apricot, Size: 14 Inch
My Dell laptop is 9" wide & 14" long. I can only zip up the back partially with my laptop in the backpack. I don't add anything else that is heavy because I'm fearful it will break. I wish it was bigger. I can fit my Apple laptop in it but it is smaller.
