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 Nicholas Serafini

I needed a larger insulated cooler bag for grocery shopping. I need to keep groceries cool, especially in the summer, for at least an hour before I get home, and the cooler bag I previously had wasn't big enough to hold all the refrigerated foods. This one has an interesting snap-down design that can be folded to about 3" flat, with an elastic strap that holds it down when folded. To open it, there are struts that snap upright to give the bag an open box shape. Two hand straps Velcro together to carry it, and there are also side straps to hold it from the sides. The only feature missing is a shoulder strap, which would have been nice. The upright snapping corner struts look like they will last with gentle use, but aren't really heavy duty.
