Glass bottles can be heavy, but this one from Contigo weighs just over 10 ounces, making it one of the lightest bottles on our list. The contoured, wide-mouth design is perfect for sipping, as well as filling your bottle with ice cubes. CONS: Less durable than others (more exposed glass), heavier than others, lid design is not our favorite Many of the bottles on our list (like CIVAGO's Glass Water Bottle and Takeya's Sure-Grip Glass Water Bottle) have straws. But Kodrine's Glass Tumbler is our favorite for its sleek, modern design, which is surprisingly leakproof.

This one is specially designed for the athletes looking for a glass water bottle. You won’t run out of water during your sport session thanks to its 769ml capacity. Also, its clever leak-proof lid can be opened one-handed and allows you to drink directly from the glass. Purifyou’s bottle isn’t only one of the best glass water bottles you can find, but also one of our favourite eco-friendly water bottles, regardless of the material. To choose the best glass water bottles, we researched dozens of options from the most popular, trusted brands. We prioritized bottles that are durable and easy to carry. In addition, we considered each bottle's capacity, lid type, weight, size, and price. We cleaned the bottles multiple times by hand and ran them through the dishwasher, noting what additional tools they needed to clean, like bottle or straw brushes. We also observed how many items needed cleaning. Leak/seal tests The bottle has a textured coating that offers a solid grip. And we like that the bottom is wrapped in silicone, for added protection from accidental drops. Plus, the wide mouth is perfect for adding ice and fun flavorings to your water.

The Zulu – Atlas glass water bottle is similar to the Ello water bottles in that it’s made of a silicone-sleeved glass body with a twist-on plastic cap that’s fully leakproof and fits in standard cupholders. Where they mainly differ is the design. The Zulu silicone sleeve has a spider-like rubberized design with textural bumps throughout the body to give you a comfortable grip. Since glass can be heavy, it’s essential to think about what size of glass water bottle you want to carry around all day. Many of the bottles and tumblers we tested ranged from 16 to 25 ounces because this was the average size and wasn’t too heavy. However, some brands sold water bottles with capacities between 8 to 32 ounces. Cleaning When it comes to getting enough ounces every day, finding a water bottle that's easy and fun to use can make all the difference. "I recommend drinking half of your body weight in ounces each day, so calculate how many times you'll need to fill up your favorite bottle," Savage says. Bonus points for a glass water bottle, as it's good for you and the environment—plus, most glass bottles can be filled with either hot or cold beverages.

After testing different glass bottles, we noticed how much smaller the Bkr bottle spout was compared to other models. This can be a deal breaker for some people who want a more effortless experience drinking an ample amount of water–it’s much harder to take bigger sips. It will also take a thinner and bendable bottle brush to clean because of the small spout. Since this is a screw top, you need both hands to open the lid. Read more… Out of all the glass water bottles we’ve tested, the Beast – Hydration bottle was our least favorite because the rubber materials made the water taste horrible. The Beast bottle has two screwtops. One that opens a wide mouth that makes cleaning and adding ice easy and a smaller spout for drinking. There’s a swing handle attached to the top, and the overall bottle has an elegant design made up of borosilicate glass and silicone. Due to the wider body of this glass water bottle, it rarely fits standard cupholders. STYLE - Having a bottle that not only does good things for your body and the planet, but also looks great is definite plus in our book. Although this bottle's large size makes it heavier than many other bottles on our list, we think the tradeoff is worth it for the convenience of less trips to the water fountain. Leakproof and BPA-free, CIVAGO's bottle comes in a range of earth tones that makes it easy to choose your favorite.PRICE - Most of the glass water bottles on this list are very affordable, so you’re sure to find a great option in your price range. They can come with straws or mouths that feature sippers for easy drinking. Sippers allow you to gulp more water, while straws are suitable for people who don’t like to lift their entire bottle each time they drink water. If you want a bottle that’s easy to use during the day for exercising or driving, we recommend a lid that opens with one touch. If you’re going to use the glass bottle for drinks other than water, like iced coffee, we recommend something with a straw attachment. CONS: Heavier than others (but it’s also higher volume than the other bottles we tested), less ergonomic than others Using a reusable water bottle and keeping it with you throughout the day can help you drink more water. Many people forget to drink water if it's not in front of them, and keeping a water bottle with you can be just the visual reminder you need. If you use an adjustable standing desk at work, try refilling your water bottle every time you switch from sitting to standing. You can also take your bottle with you anywhere and drink while at work, running errands, and traveling. Simple and versatile, this bottle can be used in several different ways. Add fruit, coffee, or tea to your water and drink using the included stainless steel strainer. You can also fill the infuser basket with tea or coffee, or just use it as a regular water bottle.
