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 wide mouth makes adding ice cubes, tea bags or fuit easy, and non-leaching 18/8 food-grade stainless steel won't retain taste or odour. This bottle comes with a straw lid that's ideal when you're on the go. It has a silicone ring to seal temperatures and moisture in, and it's compatible with any of the other Macpac Wide Mouth bottles. Please note: Carbonated or hot beverages can cause pressure buildup. Take care when opening. Straw Lids are not suitable for hot beverages.
