The beauty of buying a reusable water bottle is that you don’t have to buy disposable ones anymore. It’s better for the environment and your wallet. The Nalgene, CamelBak, and Hydroflask carry lifetime guarantees, so you’ll never have to buy another water bottle again. The Larq is rechargeable and the LifeStraw filter can be replaced. You should only have to buy a new water bottle if your current one is lost, breaks, or develops an unpleasant taste.
