Osprey backpacking backpack. Great condition. Does have some spots on the back flap from being checked once. Used a couple of times but am not backpacking in the foreseeable future. My loss is your amazing adventure. Fits a ton of stuff with or without compression packing and sits super comfortably on your back. Comes with duffel strap too. My husband still prefers to travel with his, but with 2 kids I prefer a suitcase.
