I tried the polar bottles and others and so far the Isotherm kept water the

Zefal Magnum 32oz bottle with half of it's contents pre-frozen. You
must freeze the stuff in the bottle, as a solid block, rather than
stuffing ice cubes into it. Wrap in aluminum foil to make last
longer.

Wow, my ideas sound good, I should try them.

Your Isotherm could benefit from having half it's contents
pre-frozen as a single solid bottle-shaped block also.
