Further improve the quality of your beer produced using the Catalyst with this custom designed cover. Thick 600D vinyl laminated canvas covers your entire fermenter, eliminating UV exposure and any skunking that comes with it. Reinforced cross stitching and integrated carrying straps make moving your beer easy (as easy as moving 50 lb of beer can be!). Thick construction also acts as insulation, reducing temperature swings, and a handy quick-view flap lets you monitor fermentation without removing the jacket.
