Mountain Warehouse BPA Free 1L Plastic Bottle - Leakproof Screw Top Lid Water Bottle

Product Information

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.

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. 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.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. 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. 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. 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: 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).

There are almost 30 colors and patterns to choose from, including bright gradient and marble printed options. And we love that the 64-ounce size costs almost the same as some of our other recommendations, making the Iron Flask a solid value. Just note that this water bottle is hand wash only and can't go in the dishwasher. 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. to 5 stars: These are the best stainless steel water bottles we tested. We recommend them without reservation. verifyErrors }}{{ message }}{{ /verifyErrors }}{{ This lightweight bottle features a sleek, stylish design that comes in almost 40 colors and patterns, from solid hues to botanical prints. We love that it's leakproof, with a secure, screw-on lid. Available in three sizes (9 ounces, 17 ounces, and 25 ounces), the narrow silhouette makes this bottle easy to carry with you, sliding in most bags and cupholders with ease. The bottle's slim design is easy to hold and fits in most cupholders. This, combined with the handy carrying loop that's attached to the lid, enables us to bring this bottle almost anywhere. However, it did not pass our drop tests, denting and leaking after it hit the floor. Even so, we still recommend this bottle as a convenient, mid-sized option with an effective filter. 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." 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.

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. While the design may seem basic, we love how easy it is to sip from this bottle's wide mouth. It's also leakproof, for a tight seal you can rely on while traveling your favorite trails. But we noticed it tends to dent easily, so you may want to invest in a silicone sleeve from the brand to protect the base. 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. 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.

How we tested

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 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. We were initially impressed by MIRA's 17 Oz Stainless Steel Vacuum Insulated Water Bottle because of its leakproof seal. But it dented easily, and its heavy weight made it uncomfortable to hold.
