I've used it about twice since I bought it, and it's in clean condition with no stains or damage. - Brand: mont-bell - Capacity: 4L - Color: Gray - Material: Nylon - Design: Roll-top This bag is for carrying out trash generated in the field, such as used portable toilets and garbage, by attaching it to a pack. It has high waterproofness, and the opening is folded over three times and secured with a buckle, providing excellent airtightness. In addition, the rounded bottom shape prevents trash from accumulating, making it easy to clean. It comes with a belt that can be attached to a pack. Thank you for looking.
