Zojirushi's high-quality double-wall stainless steel vacuum insulation construction allows the bottle to keep beverages hot or cold for hours. The tight-fitting flip-open lid with a safety lock makes drinking from the bottle easy and prevents beverages from spilling. The 2-step lid release process prevents excess condensation on the stopper from being flung off while the lid opens.

Tight-fitted flip-open lid keeps beverages hotter or colder. Easy-to-clean double layer non-stick coated interior enhances durability and provides greater protection of the stainless steel against salt-containing beverages like sports drinks. Air vent on the mouthpiece allows beverages to flow out smoothly, without gushing or overflowing.
