Best waterproof Cooler bag for lunch

We used this waterproof cooler bag for hiking and loved how comfortable it was to slip over our shoulders and carry. The exterior is made of a 600-denier polyester shell that’s waterproof. The zipper is completely watertight with welded seams, so leaking isn’t on the menu .

The two side handles aren’t the most comfortable to grab, and we wish they weren’t adjacent to the shoulder straps’ attachment points. The center magnetic handle is smooth and nice to grab. 

The soft dry cooler bag did well on a weekend road trip to climb and camp out, but wouldn’t be able to retain ice for longer durations. Our ice retention test corroborated that experience, showing the cooler is capable of holding ice for nearly 2.5 days.
