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.
