This ultra-lightweight bottle features an amazing piece of technology - it cleans itself and the water (a bottle that helps with the washing up, what more could you want?) using a UV-C LED light that neutralises germs. We felt like we were drinking some of the purest water in the world. With a chic stylish design, it’s easy to use and transport - everything we want when setting out for our daily walks.
One of our favourite things about this bottle is it's able to go in the dishwasher, so cleaning is a breeze. It'll also keep water cool for up to 18 hours and hot drinks warm for six hours. And you can feel good about yourself buying one of these bottles, as they're made from 67 per cent of recycled materials and every one sold funds the collection of 1,000 water bottles from the ocean.
