Use this insulating jacket to regulate the fermentation temperature in your 55L FermZilla.

The jacket alone will help keep your fermenter warm in the colder months, or you can add a heat belt if the fermentation heat isn’t enough to maintain temp. Conversely, you can freeze bottles of water and put them inside the jacket to keep the temperature from getting too hot.

The jacket has the added benefit of protecting your fermenting beer from harmful UV light.

Features a single sided zipper and draw string bottom.
