FlexiFreeze is a sheet of 88 encased cubes filled with 100% water.  There are channels which enable the sheet to be flexible and fold-able even when frozen.  Water (when frozen), actually absorbs 35% more heat, pound for pound, as it thaws than chemical gels. FlexiFreeze coolers are high performance - the only coolers with real, purified ice built right in. A blanket of ice surrounds your food and beverages keeping them refrigerator cold for optimal freshness, safety and taste.  FlexiFreeze is the cold without the wet.
