While this bottle keeps our water cold for hours, preserving ice cubes overnight with ease, Owala notes that it's not meant to hot hold beverages. Instead, we recommend S'well's Water Bottle for your tea or coffee. When looking for a stainless steel water bottle, choose one that's well-insulated, in a size that's convenient for you. We researched and tested some of the most popular stainless steel water bottles on the market to find out which ones are truly the best. We also tapped experts, including Todini, for their opinions on which features set the top water bottles apart. In testing, we found that this bottle didn't keep our water as cold over time as Takeya's Actives or Thermoflask's bottles did. But with only a few degrees difference, we still think it's a solid option. We're also fans of the lid, which has a unique design that's a delight to drink from. verifyErrors }}{{ message }}{{ /verifyErrors }}{{ Verywell Fit articles are reviewed by board-certified physicians and nutrition and exercise healthcare professionals.

For a slim bottle that can slip into the cage on your mountain bike or indoor cycling bike, we recommend this Healthy Human's Thermos. Its double-walled insulation keeps our water cold for hours, while the lid has a convenient handle for rehydrating while you're on the go. to 4.7 stars: These stainless steel water bottles are excellent—they might have minor flaws, but we still recommend them.

Purist's Mover Vacuum Water Bottle has a stylish, compact design. But for how expensive it is, we wish it could go in the dishwasher. The cap is also hard to open and leaked when we dropped the bottle from waist height. Water bottles can range in size from 12 ounces all the way up to 84 ounces (or even more). "When choosing a stainless steel bottle, consider what you’ll be using it for," Todini says. "If you’re active in sports choose a lightweight and slim bottle that can easily be carried, or if it’s your everyday water bottle choose one that fits in your bag or car’s cup holder." Single-walled insulation means the bottle is made from a single layer of stainless steel. You won't find any single-walled bottles on our list because they don't stabilize temperature very well, meaning your water won't stay cold over time. to 5 stars: These are the best stainless steel water bottles we tested. We recommend them without reservation.

A 64- to 84-ounce stainless steel water bottle is a great option if you're playing tennis or a sport where you might be in hot weather for several hours and want your water to remain cold. A 17- to 32-ounce water bottle is easier to carry with you during everyday activities, like going to work or the gym. Sleek and well-designed, Hydro Flask's Standard Mouth Bottle is our recommendation for a stainless steel water bottle with a wide opening that's easy to drink from. We like that the mouth is the perfect width and features a comfortable lip. The size and shape makes adding ice, fruit, or other ingredients to your water a breeze. The double-walled insulation kept our water icy cold. Thermoflask notes that the bottle will chill drinks for 24 hours or keep them hot for 12, making it a solid choice for your morning coffee or tea. The attached handle is easy to hold, although we wish it could be folded down when not in use.For a stainless steel water bottle that comes with a filter built in, we love this option from Brita. It filters out unpleasant tastes and odors, for fresh-tasting water with every sip. We like that the filter is included at a similar price to most other bottles on our list (although you'll need to replace it regularly to reap the full benefits, according to the brand).

To test how portable the water bottles are, we try fitting them in a standard car cupholder and carry them around using their handles, if applicable. Finally, we drop each water bottle from waist height six times (three on its side and three on its lid). At the end of the test, we give each bottle a rating from 1 (would not recommend) to 5 (would recommend) in 6 key categories: drinkability, seal, portability, insulation, durability, and overall value. We liked that Hydro Flask's 24 oz Lightweight Trail Series Water Bottle has a convenient handle and a sleek silhouette that fits in most cupholders. However, when we dropped it, the lid almost flew off, and the slippery, shiny finish was tough to hold. We love that this sturdy bottle doesn't leak, even when dropped or flipped upside down. But unlike Takeya's Actives bottle, it did dent after multiple falls. Available in a range of jewel tones and sizes, you can grab a smaller bottle for sitting in your car's cupholders or a larger size to cut down on your refill trips. Just note that the larger sizes can start to feel heavy, weighing between 1 and 2 pounds each.We often test water bottles in the Verywell Testing Lab. To find the best stainless steel options, we first research dozens of popular models from the most trusted brands. We also ask experts like Kristina Todin, RDN, a registered dietitian nutritionist, for her advice on how to shop for a stainless steel water bottle that's both functional and durable.

We love the sleek design, which has a modern, angular shape and comes in a variety of bright colors and patterns. The 16-ounce capacity is solid for everyday sipping, and the low-profile lid is completely leakproof, for added peace of mind. and below: We don't recommend stainless steel water bottles with this rating; you won't find any on our list. Water Bottles We Also Tested Next, we select a set bottles to test for ourselves. To see how effective each bottle's insulation was, we fill them with ice and cold water. We use a liquid thermometer to measure the temperature of the water immediately after we pour it, 3 hours later, and 6 hours later, as the bottles sit on a sunny windowsill. Lainey Younkin, MS, RD, LDN, is a registered dietitian always looking for ways to help her clients drink more water. She has personally owned many stainless steel water bottles because she can’t stand lukewarm water and loves any bottle that keeps her H20 ice cold for hours. But that's not all the lid has to offer. Use one hand to push the button, and it flips open to reveal a two-in-one spout. We love that you can sip from the straw or use the wider opening to grab a big gulp of cold water without needing multiple lids.

Made from 18/8 pro-grade stainless steel, this Hydro Flask is BPA-free. But while it kept our water cold for three hours, we noticed the temperature had increased by 8 degrees after six hours—meaning this bottle's double-walled insulation isn't effective as others we tested. If insulation is important to you, we recommend investing in Takeya's Actives Water Bottle or Thermoflask's Water Bottle instead. The 64-ounce Iron Flask Water Bottle is our favorite large capacity option if you want to space out your refills. (However, we also stand by the other five sizes if you're in the market for something smaller.) We love that it comes with three different caps: a straw lid with a carrying loop, a flip lid, and a stainless steel cap that covers the bottle's wide mouth opening. The wide mouth opening allows us to add ice cubes, while the spout lid ensures we can sip without soaking our shirts. Combined with the handy carrying loop, we recommend this bottle as your everyday go-to, especially if you work out often and need a basic bottle for the gym. To help you stay hydrated, especially during busy days, we recommend investing in a functional water bottle that you can bring with you to the gym and the office. Stainless steel water bottles keep your water cold for hours, are better for the environment than plastic, and aren’t prone to breaking like glass water bottles can be.
