Not only does the Stainless Steel Growler maintain the temp of your beverage, but it's also HUGE! This 64-oz. Growler holds darn near a six-pack's worth of 12-ounce beverages. It's vacuum insulated to prevent heat and cold transfer. That means the exterior stays cool to the touch and condensation-free, no matter the contents. Great for coffee in winter; perfect for cold drinks in summer.
