The stainless steel 24bottles Clima bottle is the reusable and safe stainless steel bottle that keeps your drinks cold for 24 hours and hot for 12. No leaks and a perfect size for your comfortable daily hydration. The natural thermo-regulation of steel can be combined with the closure wide enough to put ice and keep the drink cold when you need it. You can combine it with a bottle cage to tie it to your bike or your backpack. And think that every time you use one of these reusable bottles instead of a plastic bottle, you will be avoiding throwing CO2 into the environment .
