ESA COOL V4 cooler bag made of waterproof material, with net and rod. - Model Name: ESA COOL V4 - Material: Waterproof material - Accessories: Net and rod - Color: Silver Thank you for viewing. I purchased this a few years ago and used it once, but haven't used it since, so I'm putting it up for sale. The main zipper is rusty and doesn't move, but the insulation and small window can be used without any problems. Please consider the above information and the fact that it is a used item. No claims and no returns, please.
