Made from EVA, this is a lightweight and durable cool bag, designed to keep your bait or food and drinks cool on hot days. The Bag is waterproof with welded seams to ensure the contents stay dry. EVA is an ideal material for use in saltwater fishing, it is resistant, easy to clean and will not degrade over time. It is a semi-rigid design so it maintains its shape and does not collapse, but can be compacted when traveling or for storage in other bags and boxes.
