You can rent three different sizes of coolers along with soft or hard ice packs. 9 quart cooler is ideal for short day trips and one or two people. 16 quart cooler is suitable for a small family for a few days. If you are planning on packing food and drinks for a bigger crowd, you should then rent our largest 30 quart cooler. These three sizes provide adequate flexibility. For example, you can rent a large 30 quart cooler to keep at your campsite and a small 16 quart cooler to take with you when fishing.
