If you bring it to the gym or use it while on your treadmill, it needs a spill-proof cap. If you sip water when you’re on the road, you need a reusable bottle that fits into the car cup holder. Treehugger's Margaret Badore performs a drop test on a Corkcicle water bottle, which didn't make it onto our list of recommendations.Ĭonor Ralph / Treehugger What to Look for in a Reusable Water Bottleīefore you buy, think about how you’ll use it. To make our final list of recommendations, we only include products with a star rating of 4.3 or higher. We then assigned value and sustainability scores, to calculate an overall star rating. In addition, we took into consideration real-world insights from our editors about the bottles they've been using for years. Finally, we conducted drink tests standing still and while walking. To evaluate portability, we rating how easily a bottle fit in one's hand, and if it fit in standard cupholders and backpack pouches. To test the seal, testers looked for spills and leaks after shaking full bottles around in a backpack. To measure insulation, we took temperature reading of cold water after 3 hours. To measure durability, we repeatedly dropping bottles from different angles from a height of 3 feet, to recreate knocking a bottle off a table. We performed five tests and assigned 1-5 a rating to quantify the results of each one. We spent a full day testing 26 water bottles at our test lab in New York City, to gather both qualitative and qualitative data using a scoring methodology written up ahead of time. However, if you prefer the taste or feel of drinking from glass, check out the elegant Porter Water Bottle. Our top pick for a reusable water bottle is the Yeti Rambler, which kept water cold and got top marks for durability. We also like its elegant design, and that it's dishwasher safe. However, we feel confident giving the Porter a fairly high durability score, because one Treehugger editor has owned this bottle for years and noted that it's survived a number of real-world drops on tile and wood floors. Our lab manager requested that we didn't drop test any glass bottles for safety reasons. Sleeves are less concerning because they don't actually come into contact with the beverage. Though we usually stay away from silicone, you'll be hard-pressed to find a glass bottle without a silicone sleeve (they do help to grip it easily and prevent breaks). Our testers gave it top marks for its seal and said it felt nice to drink from, but didn't insulate as well as the double-walled metal bottles. Glass on the other hand is inert, so water and other beverages don't pick up any off tastes from this bottle. This glass bottle is great for those who prefer drinking from glass rather than plastic or metal, which sometimes changes the taste of water or other drinks.
