You’re nothing without water.A reusable water bottle that is good-looking and functional is vital for anyone who wants to remain hydrated while reducing disposable-bottle waste.After putting in more than 150 hours of research—and testing more than 120 bottles—since 2014, we’ve chosen the six best water bottles in a range of materials and styles and for various situations.They include our most versatile pick; a bottle with an attached lid; a bottle with a straw; a bottle you can open one-handed; a glass bottle, if you’re averse to plastic; and a bottle that protects against transferred flavors. We also have some plastic bottles we trust and bottles that are decent for travel.
