The large capacity 64 oz BOSS was named "Best Insulated Growler" by Craft Beer and Brewing Magazine. The BOSS stainless steel growler features our signature TriMax™ Triple Insulation and keeps drinks cold up to 150 hours and hot up to 24 hours. The Reflecta™ lid is insulated and lined with stainless steel, enhancing temperature retention and preventing liquids from touching plastic. The dual-opening lid is easy to grip, has a wide mouth for easy filling, and a small mouth for smooth pouring.
