I have been on trips to the desert when they were used to keep water cool. The tan color does not seem to absorb much of the heat from the sun. They can also be used to keep other things hot. They are 17 x 9 x 20 high and can be used as a padded container for things that need to be kept from getting bashed, cameras, telescopes, and such. They can be used to keep your clothes in or any other things that need to be contained on an outing. Great for the whole lunch/picnic thing. YMMV I am getting two (they come in pairs in this offering) as I can donate the other one to a group raffle for another group I am in. They are highly prized by desert dwellers and 4x nuts. Morris |
