Chill Wrap™ Ice Replacement (or gel ice or slicka pad or coolant) uses the water-loving (hydrophylic) action of a special salt in a spectacular way. Have a look at the following short video for a complete explanation.

In short, Chill Wrap works by:
Absorbing water through the fabric surface
Trapping the water in a damp gel that can't escape through the fabric
Freezing the gel to make ice
Because of the cellular structure the ice remains flexible
It can't leak when thawed because the gel particles are too big to fit through the fabric.
