I absolutely love my Icemule cooler bag! Of course, it’s a fantastic cooler, but I use it for SO MUCH MORE than that!! It’s my go to for a water and sand resistant dry bag for my towels, keys etc and because it floats, I don’t have to worry about it falling into the water. I appreciate the durability. I’ve attached it to my backpack for extra storage and it’s been through airport after airport. I have a larger Icemule that I carry my heavy laptop In. I was worried it might rip the bag, but not at all. I slip the laptop out and blow up my Icemule and use it as my travel pillow. When I get to my destination, I use my Icemule to hike to the market. I could never carry a heavy cooler that far and because it’s hands free, I can do my shopping. It keeps my groceries cold PERFECTLY! I purchased 2 9L for my sons. One rides motorcycles and the other snowboards. The 9 L is the perfect size for both.
