New and improved BrewZilla Gen 4 Neoprene Jackets for more stable mash temperatures and heat retention. Now made with 8mm thick neoprene, improved recirculation pipe insulation on both the boiler and the recirculation camlock arm.

If you brew outside where it is cold or windy, the Neoprene Jacket/Parka is a must-buy! Don't lose that heat to the atmosphere!

You could adapt this to a 65L BrewZilla 3.1.1 or 65L DigiBoil, you will just need to cut a hole for the ball valve as the Gen 4 has it on the lower panel.
