Some products were simply destined for greatness. The 64 oz Hydro Flask Growler, the world's first vacuum insulated beer growler, is 64 ounces of pure insulated joy. Though designed principally to keep beer chilled, carbonated and optimally contained between destinations, the Hydro Flask Growler also doubles as a coffee carafe, lemonade stand and whatever else you may dream up along the way. The double wall vacuum insulation will keep liquids icy cold for up to 24 hours while hot liquids remain steaming hot for up to 12. Double wall also means no condensation, so your Hydro Flask bottle will never sweat or perspire. Hydro Flask's 18/8 food-grade stainless steel interior is non-porous and rounded corners help eliminate bacteria buildup, as well as unwanted odors and flavors. The wide 2.2" mouth is as easy to pour out as it is to pour in, and the BPA-free, PP#5 flat cap is insulated to further protect your beverage from outside temperatures. Hydro Flasks are made from 100% recyclable materials and are backed by our lifetime warranty. Look for the H-guy and Hydro Flask logo to ensure you're getting the market's premium insulating beverage bottle.
