[Low-Tech] [High-Tech] Portable cooling: higher-TL replacement of water jugs?

The amount of heat from water that is 12C cooler than you body temperature is just over 2% of the amount of heat you'll eliminate by sweating away the same amount of water, so in absolute terms it is not significant. However, it's cooling available exactly when you want it, and not subject to the limitations of sweat (which can shut down in cases of heatstroke).

In fact, the bonus to survival might really be a bonus for having heat stroke treatment available.
