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.
