ThermaFreeze Fours originated from a simple “bigger is better” concept from customer feedback and requests for larger Therma-Cubes. While not as flexible for wrapping smaller items, the new fours are wonderful when working in conjunction with our original ThermaFreeze. While Fours can stand alone in any environment, to achieve great results use the Fours on the top and bottom of any arrangement and wrap individual items with original sheets. Now available in two retail packages depending on your need, we offer a 4 pack which gives you 12 pounds of ThermaFreeze as well as a Cooler Pack designed to work with most common coolers and provide unparalleled performance. (For extra large coolers, more than one cooler pack may be necessary.)
