This backpack is what every traveler needs to avoid charges for carry ons with airlines like Frontier and Spirit. I used this for a 3 day trip and it fit everything perfectly. I flew Frontier to my destination, and Spirit home. This backpack fit perfectly under the seat on both airlines. 10/10 would recommend for anyone looking to maximize the space allowed with a personal item to avoid fees.

Great product, would recommend!

….Meant to stand up on its own like a jansport backpack would. I added some stiff cardboard to the bottom to help support. Might work.

Love how much room there was. I had plenty of space fir more items in the bag.

This came unzipped just as my husband was walking in the airport .... That was not fun. He just purchased this for a carry-on and we will have to buy a new one.... Because we cant trust it to do what it was literally made to do.

It was for my son and he likes his new bag.
