This is an ultralight backpack in good used condition. It has a few dark marks on the material but I didn’t try cleaning them off. It’s a frameless pack so it weighs roughly 1 pound 9oz. The torso size is medium. The pack has shoulder load lifters and a spot for a water bladder. It has all the features of the high end ultralight backpacks. There’s a topper that can be removed if you choose. See images
