I purchased this at a North Face shop! I've only used it a few times for field trips and trips to the park, so it hasn't been worn much and is in clean condition with no noticeable stains! It's very light and allows you to use both hands, so I think it would be great for festivals and events! This is a medium-sized 4-liter waist bag that can store thin windbreakers, snacks, valuables, etc. It has storage space on the front and back for convenient organization of your belongings. It can also be worn diagonally across the body, and features a one-hand adjustable single-pull strap. Recycled materials are used for both the main fabric and the reinforcement fabric, showing consideration for environmental protection.
