This is a MAMMUT drink holder. Color: Black / Orange A lightweight and practical bottle holder for the Lithium backpack series. The outer fabric is made of recycled nylon, and the lining is made of recycled polyester. It can be attached to the hip belt or shoulder strap of a backpack. Because it's black, it's easy to attach to any backpack. I haven't used it much, so I think the condition is good. However, please understand that this is a used item before purchasing.
