The Stainless Steel Ultimate Growler is the professional choice for transporting fresh draft beer. With a massive 2-liter (67 oz) capacity, it features a heavy-duty, double-wall vacuum insulated body that keeps beverages ice-cold for up to 24 hours. Unlike glass growlers, this stainless steel version is unbreakable and completely light-proof, protecting your beer from harmful UV rays that cause "skunking." The swing-top lid with a silicone gasket ensures a 100% airtight, pressure-safe seal for carbonated drinks.
