A reusable water bottle is a simple solution to throwing away plastic bottles, but finding the perfect one for your needs can be a bit tricky. Some bottles are on the larger side, while others are insulated. A few have built-in straws, and others come with sport caps. We’ve got the seven best water bottles to keep you hydrated this year on all of your outdoor adventures.
Best Overall: Hydro Flask Double Wall Insulated Water Bottle
If you want to keep your iced tea cold or your coffee hot literally all day, invest in the Hydro Flask Double Wall Insulated wide-mouth water bottle. Be warned, though, hours after you fill it up with a hot drink, it will still be scorching, so watch your gulping. Hydro Flask claims that cold liquids will stay cool for up to 24 hours; hot liquids will stay hot for up to six hours. The insulated water bottle comes in a variety of sizes (18, 32, 40 and 64 ounces) with each wide mouth opening measuring 2.28 inches. The smallest size is 8.1 inches high, 2.91 inches wide and weighs 11.6 ounces; the largest size is 10.4 inches high, 4.7 inches wide and weighs 32.1 ounces. The bottle is made from stainless steel and is leakproof and sweat free. Compatible caps include a regular twist-off lid, a flip lid for drinking and a straw lid for sipping. Colors include black, blue, green, gray, orange, red, teal and pink.
Runner-Up, Best Overall: CamelBak Eddy
For those who want a straw with their water bottle, opt for the exemplar CamelBak Eddy. The sleek water bottle holds just over 25 ounces of liquid and fits in most car cup holders, as well as backpack side pockets. A loop top offers easy carrying options and the integrated straw and bite valve provide a fast flow without having to tip up the bottle (ideal for faster-paced activities, such as running or the gym). The bottle is BPA-free and dishwasher safe. Colors include a variety of purples, blues, reds, greens, oranges and grays. The bottle is 10 inches tall, three inches wide and weighs 5.4 ounces.
Best for Outdoor Activities: Nomader Collapsible Water Bottle
Whether you’re hiking, biking, or camping, if you’re spending a lot of time outdoors, it’s imperative you stay hydrated. This 22-ounce, BPA-free silicone bottle was made for on-the-go use thanks to its shatter-proof, leak-proof design which includes an ergonomic strap for hands-free carrying. A sealed twist cap ensures your mouthpiece stays germ-free and once you’ve exhausted your reserve, you can easily collapse the bottle, roll it up, and stow it away in your backpack or pocket. The bottle is made of 100-percent food-grade materials and can accommodate both hot and cold drinks. When you’re done using it for the day, you don’t even have to worry about washing it by hand — the durable design is dishwasher safe. Pick yours out from a variety of colors including blue, green, red, orange, and white.
Best Wide Mouth: Nalgene Wide Mouth
The Nalgene Wide Mouth water bottle holds 32 ounces of water and fits in most packs’ side water bottle holders. It’s dishwasher safe, BPA-free and can loop onto a backpack strap or a purse. The lid locks on with a leakproof design and the entire bottle is said to be impact resistant. The bottle is 8.25 inches tall, 3.5 inches wide and weighs 6.25 ounces.
It is available in a variety of colors, including pink, blue, teal, red, purple, yellow, as well as super hero characters, flowers and hearts, and a flag design. Made in the USA.
Best Glass: Lifefactory Glass Water Bottle
The Lifefactory 22-ounce Glass Water Bottle is a solid glass option that is protected by a non-slip silicone sleeve that also helps prevent breakage (though doesn’t always hinder it). The easy flip cap with a narrow mouth also makes this an ideal bottle for kids, but it will leak if not closed properly. Plus, the funky dot pattern and round carry handle make this bottle a bit more exciting than others on the market. The bottle is BPA-free and dishwasher safe. Colors include lilac, blue, raspberry, red, purple, transparent and turquoise.
Best Stainless Steel: Kleen Kanteen Stainless Steel Bottle with Sport Cap
The Klean Kanteen Classic bottle is a fully stainless steel option that comes with a sport cap for quick, easy drinking with no splashing. The cap also has a loop for easy carry or to clip a carabiner on. The bottles come in 18, 27 and 40 ounces, with the smallest being an ideal bottle for kids (8.9 inches high and 2.9 inches wide; 6.4 ounces). Colors include blue, purple, pink, orange, teal, yellow and silver in durable, lead-free paint.
Best Flat: A5 Memobottle
If you’re an over-packer with a tendency to try and cram a last-minute water bottle in your bag then you may want to consider a flat option. Rather than trying to eke out space for a conventional bottle, reach instead for the 25-ounce A5 Memobottle. The bottle's flat 9.6 x 5.8 x 1.2-inch design easily slides into purses, briefcases, laptop bags (don’t worry — it’s fully leak-proof), and other tight spaces you wouldn’t normally be able to fit one. The Aussie-made reinvented bottles are so well regarded that they were even included in 2016 Oscars goodie bags.
Best Infused: Bevgo Infuser Water Bottle
Like to take your water with a twist? This 32-ounce Bevgo bottle comes with a large infuser that can be packed with fruits, veggies, detoxifying herbs, and other immune and digestive system-boosting ingredients. The BPA-free design features a flip-top release, an extra latch to ensure it doesn’t leak, a rubber grip for easy carrying, an ice gel ball to keep your beverage cool, and an integrated hydration tracker to make sure you’re conscious of how much liquid you’re consuming throughout the day. The bottle also comes with an insulation sleeve to keep your drink cool and it’s also printed with the same hydration timeline. Reviewers note that this unique addition makes consuming your recommended 64 ounces of water a day a complete breeze.
Best for Travel: Platypus Platy 2-Liter Ultralight Collapsible Water Bottle
When you are trying to pack as light and minimalist as possible, the Platypus 2-Liter Collapsible Water Bottle is the best option. It holds 70 ounces of liquid and weighs 1.3 ounces, plus, once empty, just fold or roll it up and squash it in your pack. The bottle is made from a flexible, BPA-free soft plastic that doesn’t compromise durability. It is shaped for easy pouring and is 13.8 inches tall and 7.5 inches wide. It comes with a simple screw top cap to keep liquids secure.
Best Filtration: LifeStraw Go Water Bottle
Although there are cheaper options for a filtration bottle on the market, the LifeStraw Go Water Bottle doesn’t cost too much, but is an award-winning filtration system that does filter out everything you don’t need. In the bottles that have a one-stage filtration system, dirty water gets poured into the bottle and sucked up through the integrated LifeStraw, which uses hollow fiber membranes that filter out nearly 100 percent of waterborne bacteria (such as E. Coli and salmonella) and waterborne protozoan parasites (such as Giardia). With the two-stage filtration system, you get the same filtration, plus a carbon filter to reduce odor and chlorine. The LifeStraw can filter up to 1,000 liters of water; the carbon capsule filters up to 100 liters of water. The bottle holds 22 ounces of liquid, is leakproof, BPA-free and comes with a straw and valve for splash-free sipping. The bottle is 10 inches high and 3 inches wide; the one-stage filtration bottle weighs 5.9 ounces and the two-stage filtration bottle weighs 7.8 ounces. Replacement filters are sold separately. Colors include blue, green, gray, pink and purple.
