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. While Takeya's Actives bottle ultimately won out, we also highly recommend this option from Thermoflask. We love that, for a similar price, this bottle comes with two lids—one with a spout and one with a straw—so you can choose your preferred method of sipping.

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.Most bottles on our list have double-walled insulation to keep your beverage hot or cold (more on how this works later). But Corkcicle's Canteen has triple-walled insulation, for even better results. This bottle excelled in our temperature tests, lowering the temperature of our ice-filled water by 5 degrees after six 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. to 4.7 stars: These stainless steel water bottles are excellent—they might have minor flaws, but we still recommend them.
Drinking enough water has plenty of benefits: “Staying hydrated is key for not only your body’s performance, but also mental clarity and productivity," explains Krista Todini, RDN, a registered dietitian nutritionist. Although the exact amount you should be drinking varies, it's safe to say that adding another glass or two to your daily routine is a good idea for most people. In total, we tested over 20 water bottles in the Verywell Testing Lab—but not every product scored high marks. Although we liked some aspects of these stainless steel water bottles, each left something to be desired: 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.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. 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. Triple-walled insulation works the same way, except there's a third layer of steel or copper (creating two vacuum layers). S'well's Stainless Steel Water Bottle uses triple-walled insulation to keep drinks cold for 36 hours and hot for 18 hours. Like Corkcicle's Canteen, S'well's Water Bottle features triple-walled insulation—perfect for keeping your tea or coffee hot all morning long. The brand claims the largest bottle can keep drinks cold for up to 48 hours and hot for around 18. While we didn't test the full extent of this range, the bottle did perform well in our temperature tests, keeping our water fresh and cold after three and six hours.
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 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.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.
