Rather than having to one hand it on your bike or deal with a growler crushing your spine through your backpack or messenger bag, our growler caddy securely fastens to your top tube and has secure leather straps that hold the front and the back of the growler tightly in place. Made from full grain leather right here in Milwaukee, WI, the Fyxation Growler Caddy is the perfect accessory for the craft beer enthusiast in your life. Designed and made by Fyxation and designed for transportation, our growler caddy will work with a traditional 64 ounce growler.
