This bottle is a travel coffee mug, a thermos jug and a water bottle in one. Three layers of vacuum-insulated stainless steel means that ice will stay frozen for 2 days, hot drinks hot for 12 hours and cold drinks cold for over 24 hours. A robust, BPA-free lid prevents leaks, drips or spills - no matter what the day holds for you. The lid seals the bottle, with a rubber seal and a robust mechanism for added protection.
