Keep hot liquids hot for up to 20 hours and cold drinks cold for just over two days with this classic, insulated steel water bottle. No shattering, rusting, leaking, warping, or leaching toxic chemicals and unwanted nastiness into your beverages. Haul it around with the loop cap to aid daily hydration; throw it in your ski pack full of warm, salty broth or cocoa; or fill it full of hot water wrapped in a wool sock at the bottom of your cold-weather sleeping bag.
