Coleman H40 W27 D15, 15 liters. It's a size that can fit A4 files. Purchased about 6 years ago. Used about 3 times for my child's field trips (town use), then stored at home. There are slight, unnoticeable color variations on the reflective material and a mark where a name was erased on the inside of the outer pocket (*_*). Otherwise, I believe it's in clean condition. *Please allow for slight errors due to amateur measurements. ● I will fold it compactly before shipping. ● Please only purchase if you understand that this is a used item. ● I apologize, but I cannot accommodate price negotiations. ● There are no smokers or pets in my household. *Thank you for looking.
