Preowned, in nice condition. This is a small backpack, about 10” tall and 8” across the front. It’s about 3” deep. The arm straps are about 18” long at maximum. It has a small bag on the front that can be detached and used as a bum bag. This is about 4” x 7” and 1” deep. The strap for this is about 26” long maximum. I assume that this is really made for a child. An adult could use the backpack over one arm but probably couldn’t wear it. Please see photos.
