WildThings backpack I believe it's around 25 liters. As you can see by comparing with other sellers' photos, the original straps, etc., are missing. The front strap is also missing, but it's still in a usable condition. The fabric is sturdy, and I don't see any scratches or weak spots, but there is some fading due to age. There is also a slight storage odor. Please purchase only if you understand the condition shown in these photos. It will be folded as small as possible for shipping.
