Our insulated FLEX jacket uses high quality, extra thick, yet flexible neoprene material to insulate your FLEX from the worst ambient conditions like a hot garage or cold basement. Each insulating jacket is tailored to perfectly fit our FLEX. Our jacket was designed by a former Lululemon designer because if you're going to cover up shiny stainless steel it better look amazing. We think she did the trick!


-Reinforced stitching around all ports, legs and handles for extra strength
-Helps maintain stable fermentation temps regardless of ambient conditions
-Stops the tank from ‘sweating’ in warm weather
-Interior Velcro for attaching the optional heater
-Machine washable

Flex + jacket.

The jacket was fantastic in keeping warm out and cold in during cold crashing as well as maintaining temp during fermentation.

Nice but not perfect fit.

I have not used the item yet but did put it on the fermenter but it’s not a perfect fit close but some of the holes are slightly off.

Nice jacket

Jacket easily slid onto the tank. Decent insulation. Put an end to my drippy cold fermenter.

Great jacket

Easy to slide on, great quality, and helped maintain temperature when used with a heat mat to increase temp.

Awesome product, just like everything from spike!

This is a nice accessory to the Spike Flex I own. This helps my glycol chiller it any temp I set for it.
