Black Ice™ was designed to maximize the ice retention of any cooler while reducing freezing times. It works as an ice addition, to help refreeze top-melt and form block ice within your favorite BrüMate cooler. 

For full effectiveness it is recommended to line the bottom of your cooler in Black Ice™ and put regular ice on top. 

Recommended Configuration: For the BruTank, when using the drink tank it is recommended to use one 4lb Black Ice™ pack and one 3lb Black Ice™ pack.
