4 Best Water Bottles, Tested by Our Experts

I used to feel as if something was missing if I went out without my water bottle, as if I’d left my house without my shoes or my phone. And yet I didn’t love my water bottle. It didn’t keep my water cold enough and didn’t come in a size I preferred. After testing seven insulated water bottles for this article, though, I now have one that’s perfect for my needs—and I’m better hydrated. 

I hope this article helps you find the perfect bottle, too. Some of those we tested lived up to the hype, but others failed miserably. You can read more about how we tested these water bottles at home and in our lab, below.
