Montbell cooler bag. Used 1-2 times. Some stains are present. This cooler bag uses EVA and air cushion insulation for high heat retention and cooling effects. The outer material uses a flexible, durable, and waterproof material. Welder processing (heat welding) is applied to all joints, achieving excellent cooling effects due to high airtightness, and the absence of seams makes it easy to wash.
