They include our most versatile pick, which has elbowed its way past more well-known competition, and an inexpensive bottle with a straw, beloved for its functionality in any driving scenario.

The HYBRID is the perfect bottle to have with you day or night, keeping your drink cold for up to 24 hours.

With a soft grip silicone handle, this bottle is comfortable and easy to carry with you wherever you go. The signature feature of the Purist is a glass-lined interior that prevents tastes and odors from transferring. Its lid threads over the drinking surface, so you won’t have to put your mouth on something that’s been getting dirty in your bag all day. While we generally don’t love the feeling of threads on the outside lip, these don’t protrude much, and we quickly got used to the feeling. They’re excellent for carrying room-temperature water and that’s it, since they are poor insulators.

Another great feature of this bottle: Despite the fact that it holds 24 ounces—a capacity we’ve found to be cumbersome in a metal bottle—the Thermos possesses just the right proportions to be ergonomic and easy to carry. When you drink from a wide-mouth glass bottle, such as the Lifefactory, it can seem like you’re drinking out of a jar. 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. Plus, the cap is metal, as is the bottle, and everyone who tested this model hated the metal-on-metal sound of the cap threading into the bottle. The hybrid bottle is also designed to be sweat-proof and leak-proof, making it ideal for use while exercising or during outdoor activities.Why it’s great: This bottle has an integrated straw in the lid that features a plastic bite valve to keep it sealed (something anyone who has owned a CamelBak hydration pack will be familiar with). By reusing the bottles, you can do your part to reduce waste and play your part in a greener future.
