Boho weekender bag - personal item size!

Personal items dimensions. Have flown spirit and frontier with this bag and it fit under the seat… I even flew to Denver for 2 nights with this bag in the winter! Two interior slot pockets, one interior zipper pocket. Handles and shoulder strap. I simply have too much luggage and need to let some go. 18x14x8 *I have a cat and dog. I keep it in a room they aren’t allowed to enter , but there might be a few hairs on the exterior. I will lint roll it thoroughly before shipping
