This backpack is by eBags and is part of a line that has been discontinued, eTech. Its dimensions are 19” x 13.75” x 9” and I’ve used it as a personal item on many flights including Delta, American, Spirit, and Frontier. I’ve also checked it in and it withstood that process well. I’ve had it for 8 years and it’s been well cared for and barely has any marks, or wear and tear which highlights its durability and it will last a long time. You can easily fit 1 weeks worth of clothes in the clam shell compartment and has many pockets for organization. Comes from a smoke free and pet free home. I will wipe every surface and aspect of this backpack with hospital-grade wipes prior to shipping out.
