Flaws but not dealbreakers: To get the water flowing, you do have to bite down on this straw and hold it while you drink, which may not appeal to some people. The straw lid twists off to reveal a wide mouth that makes adding ice to your drink easy—handy if you like to keep your water cold. These bottles come in an array of colors and sizes, and our pick, the 22-ounce Takeya Actives, is the most recent size introduced to the lineup.

Perfect for travel enthusiasts and daily commuters alike, it fits most drink holders and backpack pockets with ease.When you drink from a wide-mouth glass bottle, such as the Lifefactory, it can seem like you’re drinking out of a jar. Instead, the mouthpiece is static, and the plastic piece inside releases water when you apply pressure to the bottle.

The HYBRID is the perfect bottle to have with you day or night, keeping your drink cold for up to 24 hours. Also, some people may not like that a portion of the drinking surface is exposed; the cap threads twist into the bottle rather than over the top and around the lip. Our big concern is that this bottle doesn’t roll down particularly small, so it’s up to you to decide whether the space savings are worth it. And if a product is defective, you should be able to contact the manufacturer so that the company can make it right.

The stainless steel and copper lining work together to further insulate your beverage, retain temperature, and help against corrosion. Reusable water bottles that are both good-looking and functional seem like a necessity in our modern, hydration-obsessed world. When we make recommendations for larger capacities, such design concerns are a big part of what we take into consideration. By reusing the bottles, you can do your part to reduce waste and play your part in a greener future. Unlike traditional glass vacuum linings, the Purist’s is unbreakable (and so minimal you can barely notice it), since it’s applied as a thin, spray-on coating.
