This cooler appears much bigger in the photo listed on Amazon, however it’s great for two people going on a hike to pack a decent size lunch and will keep things icy cold! I absolutely love it!Used for 1st time for 4th July parades. Worked well. Kept the beverages cold and easier to use the backpack then lug a regular cooler around.I use this when I walk on the beach with my wife, and also great when I go fishingI needed a new lunch bag for work and this did not disappointGreat cooler love it especially it’s a backpack coolerThis is perfect to take to work and put your lunch and other things in.This backpack is awesome I usually store items while in church that I can eat or drink afterwardsThe product was much smaller than described! It showed pictures of things that would fit in the backpack, realistically it didn’t work. I only gave 1 star due to the misconception of the product. If I knew it was this small, I would have paid the extra 10 dollars to get a much larger one I was looking at previously.I ordered this nice looking insulated backpack from Smouapce to try.I liked: 1. The backpack materials are decent quality 2. The backpack has 2 separately insulated compartments plus the front pouch and side pocketsI didn't like: 1. The overall capacity is less than I had expected, but it should be sufficient for a picnic for 2.The picture shows 2 wine bottles in each side pocket, but I can't fit 2 * 750ml in either side.This could be use individually as backpack or cooler. It is good to carry food when going to pinic, hiking. It is a reasonable size backpack can fit 12 500ml spring water. Comparing to a plastic cooler, as it is a backpack type with insulation, it is more flexible to load in the car. I put a bottle of 500ml frozen water into this backpack and the room tempeture is 21 celsius degree. After 8 hours, the frozen water is completely melt.
