These Drinktanks are pretty damn cool, just make sure you don’t end up in the drunk tank because you didn’t know how to stop the drinks from flowing. These 64 oz. growlers are made from high quality 18/8 stainless steel and prevent condensation sweat due to a double wall vacuum insulation design. They also feature a BPA free poly lid that’s secured by a sturdy double bail locking system – keeping your beer fresh for up to 24 hours. An optional Keg Cap (we recommend it) can be purchased to add atop your growler and make that baby flow throughout the night while keeping it fresh all day long.
