Mesh material roll-top backpack, with a stain on the bottom. Size is about 40cm in height, so I think it's about 20L. Used about 5 times, so overall damage is minimal, but there is a red stain on the bottom. It's mostly unnoticeable, but please refrain from purchasing if you are concerned. - Brand: mont-bell - Color: Black - Material: Mesh - Design: Roll-top When carried by hand, it has a zipper opening, and when used as a backpack, you can use the drawcord and SR buckle opening. Ideal for transporting wet water sports gear, as well as camping equipment. Foam padding is included in the back panel for improved comfort. Thank you for looking.
