Our Top Picks
Best Overall: MIRA Stainless Steel Vacuum Insulated Water Bottle
Made from food-grade 18/8 stainless steel, the MIRA Vacuum Insulated Water Bottle is our top pick for travel water bottles. Its affordable price-tag is especially impressive given its rust-proof, shatter-proof design and flawless functionality. The stainless steel interior repels lingering flavors and odors so that you can store coffee in the flask one day, and water the next. It is fully insulated, keeping cold liquids cold for 24 hours and hot liquids hot for 12 hours, regardless of the outside temperature.
Its slender cola bottle shape is aesthetically pleasing, and makes it easy to slip into your travel daypack. Even when filled with ice, the bottle doesn’t sweat. This feature combines with the leak-proof stainless steel cap to keep the inside of your bag 100 percent dry. Opt for a 17-ounce bottle or a 25-ounce bottle, then choose from a wide range of colors designed to suit all tastes (including matte black, coral and teal). The bottle’s only drawback is that it isn’t dishwasher safe.
Best Size: Zoku Stainless Steel Water Bottle
If you plan on spending some time outdoors and need a large water bottle that can stay cold (or hot) longer, the 25-ounce Zoku water bottle is for you. Made from double-walled, vacuum-insulated stainless steel, the bottle can keep hot items warm for up to 15 hours and cold items cold for a whopping 70 hours. The bottle has a curved, specially-design mouthpiece that’s comfortable to drink from, as well as a rope lanyard for attaching to items. It is entirely leak-proof, so you can toss it in a backpack or purse without worrying about spills. The water bottle comes in a variety of cool, metallic shades like “ice blue,” teal, orange and purple.
Best Budget: Asrisuk Sports Collapsible Water Bottle
A popular choice for only under $10, the Asrisuk Sports Collapsible Water Bottle is a reliable option for budget travelers. Made from BPA-free, FDA-approved silicone, it keeps your beverages free from bacteria while withstanding the rigors of adventurous sports and activities. It has a relatively large capacity of 27 ounces, but folds to half its size (5.1” tall) when empty and weighs just .3 pounds. This comes in handy when you’re packing for the journey to your final destination.
It’s not insulated, which means that your cold water won’t stay cold for long on hot days. However, it does have several bonus features, including leak-proof sealing technology and a wide neck that makes filling the bottle easier. Uncap the drinking nozzle when you get thirsty, then use the looped attachment to hang the bottle from your backpack, belt or handlebars in between rest stops. It’s dishwasher-safe and comes in blue, navy blue or pink.
Best Collapsible: Nomader Collapsible Water Bottle
Available in nine different colors including aqua blue, army g reen and neon pink, the Nomader Collapsible Water Bottle is made from ultra-durable, BPA-free food-grade silicone. When full, it can carry up to 20 ounces of hot or cold liquid. When empty, it rolls up into a travel-sized package ideal for tucking into your carry-on luggage or backpack. At .4 pounds, it barely contributes to your overall airline weight allowance.
The patented twist cap creates a 100 percent waterproof seal and protects your drinking spout from contamination. The neck of the bottle is wide enough to allow for spill-free filling. When full, the fabric strap loops around your wrist or attaches to your pack, leaving your hands free for climbing, cycling or map-reading. Your bottle is dishwasher-safe and can be kept in the freezer.
Best Insulated: Healthy Human Vacuum Insulated Double Walled Thermos
Crafted from BPA-free 18/8 stainless steel, the Healthy Human Thermos features a copper-coated double wall with a vacuum in between for maximum insulation. It keeps liquids cold for 24 hours, hot for 12 hours or piping hot for six hours. The double wall also stops the bottle from sweating. The stainless steel-lined lid is 100 percent leak-proof and includes a comfortable carry handle.
Although the bottle must be hand-washed, this task is made easy by its wide neck and rounded corners. It comes in a variety of sizes, ranging from 16 ounces to 40 ounces (the largest of which weighs one pound). Opt for traditional brushed steel or choose from a rainbow of different shades and patterns. The bottle comes with a carabiner and cotton bag.
Best with Built-In Purifier: GRAYL Ultralight Water Purifier Bottle
The GRAYL Ultralight Water Purifier Bottle is made for adventures in areas with limited potable water. It features a built-in purifier that allows you to fill your bottle from any fresh water source, then transforms it into safe drinking water in 15 seconds with the push of a single button. Whether you’re drinking from a river or a suspect hotel tap, the purifier removes 99.99 percent of viruses, disease-causing bacteria and protozoan cysts.
It also removes most heavy metals and chemicals. The resulting clean water looks, tastes and smells better, helping you to stay hydrated. The bottle has a 16-ounce capacity and fits into standard backpack side pockets. It comes with a replaceable purifier cartridge, which can convert up to 40 gallons of water. Available colors include black, blue, green and orange.
Best with Built-In Infuser: Fresh Fusions Fruit Infuser Water Bottle
The Fresh Fusions Water Bottle is made from BPA-free plastic and carries 24 ounces. It includes an infuser chamber, which you can fill with cucumber, blueberries or any other fruit to add flavor to your water. It’s the ideal purchase for those that don’t like water, but need to stay hydrated on their travels. A removable strainer keeps your drink clear from pulp and seeds, while the bottom-loading design lets the flavor flow until the last drop. Use the single-release button to open the locking lid, which effectively prevents leaks when closed. Your bottle comes with an insulation sleeve and an e-book of fruit infusion recipes.
Best Style: MIU COLOR 18oz Glass Water Bottle
Designed to be simultaneously eco-friendly and fashion-forward, the MIU COLOR 18-ounce Glass Water Bottle is made from crystal clear borosilicate glass. It’s shatter-resistant and free from harmful chemicals, and protected by a vacuum-sealed stainless steel cap. Fall in love with the bottle’s sleek shape, and the cutout water drop pattern of its silicone non-slip sleeve. The sleeve comes in seven beautiful pastel colors, including amethyst, cerulean and shamrock. Measuring 9.25” in height and weighing .8 pounds, the water bottle also includes a convenient carry loop.
