Review on Heather Grey/Black CleverMade Collapsible Cooler Bag: Insulated, Leakproof, Portable Soft-Sided Cooler With Room For 50 Cans - Perfect For Camping, Grocery Shopping, Lunch, And Road Trips by Pete Norris

This cooler keeps things cold for an acceptable amount of time. It’s not a Yeti or anything but it gets the job done. The best part is being able to collapse it. It fits perfect inside luggage. It fit in our "large” carry on (the one that is technically too big for most airplanes these days) and would easily fit in any midsize luggage. This was great for having a beach cooler on vacation or walking to the farmers market downtown and carrying the items back that needed to stay cool. It is lightweight and the zippers work well. I wish it came with a shoulder strap but it doesn’t. We will bring one from another cooler the next time we travel.
