Have been looking for a portable cooler to take to the beach, out on the water, etc, and this one has some decent reviews, is waterproof, floats(!) and holds ice for up to 24 hours.
All coolers are on sale not just this one, but much cheaper than Yeti or other coolers, and cheapest ive seen this one for a while.
what difference with a cool drink jug/dispenser put into a large backpacker?
