This jacket will keep your fermenter cold in summer and warm in winter.

For heating we recommend using a temp controller like this one:
MKII Temp Controller

And a heating belt like this one:
Heating Wrap Mat

For cooling you can simply freeze some bottles of water then put into the insulated bag and this will effectively cool down the fermenter.

This jacket is designed to insulate your FermZilla during the colder months to keep your fermentation at the optimum temperature. It can also be used with a heating belt/wrap to warm up the wort if the heat from the fermentation isn't enough.

Also completely blocks any light/UV to prevent light stuck beer.
