Large travel bottle with a BPA-free, leak-proof lid. Longer sparkling, longer cool – drinks stay cold for 24 hours, hot for 12 hours, and ice lasts for 2 days. Once sparkling, always sparkling – thanks to the inner coating, carbonation is preserved for a long time. Suitable for any beverage – perfect for still and sparkling water, coffee, and more. Triple thermo-insulation – 3 layers of vacuum-insulated stainless steel keep the drink temperature consistent for longer.
