OCEAN BOTTLE

EFFECTIVENESS: We loved the dual opening for easy filling and cleaning, and how the lid doubles up as a cup, though don’t be tempted to mistake the (removable) carry loop for a cup handle – easily done, but it isn’t. This keeps cold drinks cold and it can be used for hot drinks too. BPA-free. STYLE: Made from double-wall, vacuum-insulated stainless steel and recycled ocean-bound plastic, this compact design comes in a range of matt colours and is dishwasher-safe. Lightweight but sturdy and it didn’t leak or dribble when pouring. VALUE: Ocean Bottle is out to change the world via a link-up with Plastic Bank. Every purchase funds the collection of 1,000 ocean-bound plastic bottles in weight, and collectors in coastal communities in some of the world’s poorest places exchange this plastic for essentials. At £40 it’s expensive, but it should last a life-time and is helping tackle plastic pollution and poverty. PRICE: £40 from Ocean Bottle (oceanbottle.co)
