The FlexiFreeze Ice Vest is the lightest, thinnest, best performing, and most cost effective cooling vest on the market today. The patented Ice Vest uses FlexiFreeze Re-Freezable Ice Sheets to harness the cooling power of 96 pure water ice cubes in 3 ½ pounds of efficient cooling capability. Pure water is used because pound for pound, water is a more efficient cooling medium than gel packs. The vest is constructed from neoprene to provide soft, flexible, lightweight insulation. At less than 1" thick, the vest allows for maximum mobility and flexibility. Each vest is outfitted with three re-freezable, removable panels that are attached with Velcro for easy replacement. Adjustable in four places, the FlexiFreeze Ice Vest has been designed to provide a snug fit for everyone from XS to 2X. The vest and panels are machine washable when the ice sheets are removed.
