Piping hot or icy cold — this bottle has both sorted. It's vacuum-insulated to keep your favourite beverages at the right temperature. Double-wall technology prevents condensation on the outside, and the internal vacuum space maintains temperature inside. The narrow mouth makes it easy to rehydrate in a hurry, and non-leaching 18/8 food-grade stainless steel won't retain taste or odour. This bottle comes with a sports cap-style lid that has a silicone ring to seal temperatures and moisture in. It's not compatible with other Macpac insulated drinkware. Please note: Carbonated or hot beverages can cause pressure buildup. Take care when opening. Sports Cap Lids are not suitable for hot beverages.
