The thing is, even for rich people, the cooler bags are cheaper AND better, they’re lined to keep cold things cool longer, and they hold a nice square shape, the sides are stable with nothing in them, so they’re very easy to pack, and they’re super durable, for only $3. They can be washed just as easily as any other bag, and can be zipped closed.

Their fabric ones are also good size, quality, and washable, also for $3.

The $15 ones simply make no sense.
