We have these coolers specifically for our travels. They can be rolled up or flattened, making them easy to pack in your luggage without the hassle of bringing or purchasing a bulky cooler. We have various sizes that conveniently fit under the ice machine chute in hotels, making it simple to fill them up. Recently, we've been enjoying national park vacations where we fly to our destinations. We recommend these coolers to our friends and they never disappoint. When in doubt, opt for the larger size!
