We bought our first one green bottle when our daughter was constantly breaking water bottles at school, all though dinted with love her one green bottle has survived to live through another school year! Impressed with the quality we then bought a smaller version for our toddler which again isn’t in pristine condition but still works perfectly! We have just bought the epic bottle for my partners 12 hour night shifts on the railway and he’s so impressed that even with a sports cap (which we assumed would effect the insulation aspect) he’s drink is still cold when he’s finished his job even through the current heat waves! We really wouldn’t purchase any other bottle for any member of our family now after trying One green bottle! And we can also feel great about the reduce environmental impact our drinks are having
