The Contigo AUTOSPOUT® bottles are equipped with a push-button which operates the flip-up drink spout with one touch. This way, cyclers can count on a 100% spill and leak-proof drinking experience while in movement. No biting on the spout is required. This makes it not only more comfortable to use the bottle it's also more hygienic. The lid can be cleaned easily in any dishwasher (top-rack).
