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 has a small mouth for smooth pouring. Fill the BOSS insulated growler with cold craft beer from your local brewery or fresh, hot coffee at your favorite café. For a crowd pleaser, pour in chilled red or white wine and fill the infuser with wedges of citrus fresh fruit for a refreshing sangria that will stay cold all day and all night.
