Great product from a grizzly 20 hard cooler, yeti 12 hopper & 24 back flip cooler owner. The cooler has a port that lets you add air to the insulated side walls, which can improve its insulating value. Pic 2 shows black round knob upper left.

It is waterproof and did not leak. They wipe down easily. Do have to make sure it doesn't tip over, that’s the only spill we had once.

This is when i emptied it dried it up and packed it right up for a return. The leakproof claim is a blatant lie. This pos is going back as soon as we return from vacation.

There is no zipper or closure on top. It just folds and latches. If you tighten the strap it will stay in place but will choke you.

Ice packs were melted in an hour. Melted in two hours. It is not leak proof, more like leak resistant to some extent. That's about the only good thing i can say about this cooler.

The fabric does not live up to its expectations. The durability of the exterior (and now i've discovered interior) fabric is extremely poor.
