Olive green nylon backpack with zippers for excellent storage. It's large enough to comfortably hold two 2L plastic bottles. It can be folded inside out, so it can also be used as an eco-bag. The stain in the 7th photo is on the inside, so it shouldn't affect use. I received this as a gift, so I don't know when it was purchased. I have never used it since receiving it. I will fold it up small for shipping. - Color: Olive Green - Style: Backpack - Material: Nylon - Features: Zippers Thank you for looking.
