I have owned an Icemule classic model for many years and love it because it keeps ice for days and is both durable and highly portable. This year I bought one for my mom for her birthday. It turned out to be the perfect gifts. While certain coolers are performance driven, they ultimately are only useful if you have a truck for lugging them around. Icemule’s are perfect for kayak fishing, camping, farmers markets, and going to the beach. The minty green color was a hit! I will be buying ice mules for a long time. The secret is freezing ziplock gallon bags of water, they melt very slowly!
