They would have something if they developed a pod that was compatible with the "Nalgene water bottle" module, a little fatter than their 3 inch module. Those overhanging caps don't do them any good, either - they are hard to pack efficiently. I fear you can do just as well or better with stuff from the grocery store.
But it is always nice to have options.....
I would think they would snug up quite nicely at the bottom of the pack instead of attaching the insulating pad/roll at that location.
