Had the Small 10L Classic for a week now. Used it once at a fundraiser where I was parking cars for 14 hours in the hot sun. Ice did melt by the end of the day, but the water bottles remained cold. Also used it on a kayak day trip on the river. Performed perfect. Worked much better on the river than a traditional cooler. The strap is also very useful when loading/unloading and for attaching to kayak. I see this as a great gift idea for someone who loves the outdoors.
