Chill-Its Rechargeable Phase Change Ice Packs provide IMMEDIATE & LONG-LASTING COOLING RELIEF. They maintain constant 64°F (18°C) for up to 4 hours and recharge in as little as 10 minutes, in a cooler of ice water. The patented honeycomb ice pack design also eliminates stiffness. You can't freeze regular water icepacks in a cooler of ice water, and as temps rise, regular water icepacks melt and turn to warm water, so the cooling effect diminishes quickly.
Could you describe the advantage of "phase changing material" over the use of the traditional (purely water) "ice packs"?
