Staying hydrated sounds easy in theory, but a busy schedule and an on-the-go lifestyle can present some challenges. Still, the benefits of drinking enough water can't be understated. Water is essential for virtually every bodily function, including digestion, waste removal, joint lubrication, and even breathing.
Byrdie Researched & Approved
Our best overall pick is the Yeti Rambler Bottle, an expert-recommended product with an innovative cap and double-wall vacuum insulation. On a budget? You can't go wrong with a classic Gatorade Squeeze Bottle. We also love the Stanley Quencher H2.0 FlowState™ Tumbler | 40 OZ, which lives up to its viral hype.
"A safe bet is six to eight cups of water per day," says registered dietitian Jonathan Valdez. "If you're at a higher altitude, living in a hotter climate, or in intense training, you will need more."
While there's no one-size-fits-all strategy, keeping a water bottle with you can certainly help. And—bonus!—you can cut down on your use of single-use plastics.
We conducted hours of research on the best water bottles, evaluating each on design, size, material, and any extra features. After considering dozens of models and consulting with a registered dietician for his expert recommendations, we landed on these picks.

"I personally like Yeti, not for its bottle per se, as it's similar to other insulated water bottle brands, but because of the Rambler Chug Cap," says Valdez. He explains that it's more sanitary because you don't have to touch the spout or expose it to airborne contaminants. "It makes it so easy to drink and carry while hiking, going to the gym, or traveling."

The brand's NoSweat design keeps the outside dry, even when it's filled with ice-cold water. It's also conveniently dishwasher-safe.

What to Look For in a Water Bottle
Durability
Common durable materials to look for are stainless-steel, BPA-free plastic, and glass. Yes, you heard that right, glass. Many glass bottles come with a silicone sleeve that will help protect them from breaking during any accidental drops or slips.
Versatility
Make sure the water bottle you buy supports the temperature of water you like to drink. If you like it super cold, find one that's extra-insulated. If you want hot water, try to find a water bottle that works with both hot and cold liquids. Also, check out its portability. Can you clip it on your bag or fold it down? If you're storing it inside your bag, does it have a spill-proof lid to prevent any spills? Try to find one that stores well to keep your hands free.
Features
Beyond simply holding water, reusable water bottles have become quite advanced. There are some that collapse down for easy storage, some that offer self-cleaning abilities, as well as some that work with apps on your phone to track how much water you're drinking. How many bells and whistles you want in your water bottle will depend on how much you're willing to spend and your personal preferences.
