I like that the packs are flat and fit nicely in my soft-side coolers but, because of the larger surface area, they don't seem to stay really cold as long as the smaller but thicker packs. I've overcome this to some extent by stacking 3 together in the same cooler... they do stack more easily than the chubbier ones!
