The double-walled stainless steel growler keeps 1.8 litres of beer cold all day. It has two cap options, a normal wire bale cap and a keg tap cap that has a tap hose and lets you inject CO2 and release excess pressure. There's also a handle for easy carrying.
The DrinkTanks Growler has already collected more than three times its Kickstarter goal, with three weeks left, but we'll have to wait for hands on. The growler is $US65 and up depending on things like colour, and the keg tap cap is an extra $US30, but with this setup you'll never be able to say keg tap cap correctly again, so it's probably worth it.
