Perfect for safely moving your brew from kettle to final fermentation place. Constructed of durable Neoprene fabric, these Carboy Parkas are the strongest and coolest we've seen. The Neoprene is good at maintaining a temp by not releasing too much of the heat created by fermentation. If it gets too hot, the Parka allows you to drop a few ice packs inside and drop a few degrees off that ferment temp. Also great for keeping your beer out of the light. Comes with sturdy canvas straps that Velcro together at the top for easy carrying. A very sturdy zipper on the side allows for easy application and removal. Please note: Carboy not included.
