From Tap to Trailhead. The revolutionary new Growlers from Hydro Flask allow you to take fresh, cold craft beverages on any adventure, while delivering the taste the brewer indented. The Fresh Carry System is leak-proof, double-wall vacuum insulated, seals in carbonation, and is easy to pour and transport. The cap design seals tight to hold carbonation and the unique one-handed design ensures a perfect pour. 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 6. 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 mouth is as easy to pour out as it is to pour in, and the new BPA-free Flex Cap is insulated to further protect your beverage from outside temperatures. Hydro Flasks are made from recyclable materials and are backed by the manufacturer's lifetime warranty.
