Definitely not waterproof

  • Familiarity:I've put it through the wringer

Since the specs list the liner as waterproof, I felt no hesitation putting ice in this to keep some meat and dairy cold during a car-camping trip. Bad move. The ice melted a little, and the water totally saturated one of the bottom corners of the bag. I thought perhaps the cooler had soaked up some water from the outside, rather than leaked, so I tried it again, just to make sure, and it definitely will leak when ice melts in the main compartment. I use freezer packs only in it now. It's still a handy cooler for picnics or grocery shopping.

Hi Ashby,
I am really sorry to hear of your issue. What I have experienced is that the bag will "sweat" or condense on the outside sometimes, but not leak. I filled mine with tap water and let it sit out and didn't have any issues. But when I filled it with ice and let it sit out in heat the bag condensed. Still kind of a bummer, I use ziplocks with ice cubes cause I can reuse them during multi day trips. Hope this helps and sorry you had a problem.

What is the difference between this and the basic cube for $21.95?

This is a cooler, and the Basic Cube is just a storage container. Both of them are designed to fit into their Modular Hauler System.


Nice cooler

  • Familiarity:I've used it several times

I use this to haul food back and forth to my parents house about 3 hours away. It keeps everything nice and cool using just one cold pack at the bottom.
