Choosing the right insulated water bottle doesn’t have to mean choosing the most expensive one. Try to focus instead on picking a water bottle that best meets your needs, whatever they may be. Embarking on a day hike? Going camping with your family? Leaving on a kayak expedition? Mountaineering with your best friend? Enjoying a good hot drink? No matter what you’re doing, there’s a water bottle for it.
The majority of insulated water bottles stay hot for 6 to 12 hours and stay cold for between 6 to 24 hours. Choosing a water bottle also comes down to the size of your backpack, car or kayak. Most people will carry a water bottle in the side external pocket of a backpack, or store it in the cup holder of a car or kayak. You’ll therefore need to measure the width of your backpack pockets or cup holders to know which water bottle is right for you. Now, let’s review eight of the best insulated water bottles.
BEST INSULATED WATER BOTTLES REVIEWED
- Keeps drinks cold for up to 41 hours
- Stays hot for up to 18 hours
- Therma-Swell technology
TOP WATER BOTTLE BRANDS
These brands are on our radar for a reason: they know a thing or two about staying hydrated. But it helps that they excel in keeping your beverages super cold or perfectly warm, too.
In 2006, Ryan and Roy Seiders founded YETI with a simple mission: to build the cooler you’d use every day, if it existed. So they set out to create coolers for the serious outdoor enthusiasts rather than for the mass-discount retailers.
The Texas-based brand decided early on that product innovation would come from necessity and firsthand experience – not from market research and data analysis. Today, YETI products perform when it matters most – whether that be an excursion into the remote Alaskan wilderness or just getting together with friends and beverages in the backyard.
When Klean Kanteen got their start in Chico, California in 2004, it was actually quite difficult to shop for a reusable, stainless steel water bottle. Everything was plastic.
So this family and employee-owned brand created the first BPA-free stainless steel bottles and many other companies have followed their lead. But the way they see it, when it comes to creating environmentally-friendly products, the more the merrier.
From the very beginning, Klean Kanteens have been built with love— the love of adventure, the love of conserving wild places and the love of replacing single-use plastic.
The only thing Hydro Flask loves more than spending time in natural places is helping share that experience with others. That is the brand’s purpose and heartbeat – along with encouraging people to switch to reusable water bottles.
With headquarters in Bend, Oregon, surrounded by mountains, rivers, and lakes, Hydro Flask knows that Mother Nature is the best designer there is. There’s never anything extra —every choice is made for a reason. That’s the inspiration behind every product the brand designs. Keep it strikingly simple.
Thermos is a pioneer. It was the first company to develop consumer products using vacuum insulation in 1904, and has been a trusted household name ever since.
The hot stays hot and the cold stays cold. Thanks to Thermos’ durable double wall stainless steel vacuum insulated technology, as well as its superior performance and exceptional durability, you’re sure to find a bottle that fits your lifestyle. For over a century people have loved Thermos products because they make everyday life better. The little things go a long way.
S’well started with the iconic 17-ounce bottle. A triple-insulated trophy of industrial design that keeps cold cold for 36 hours and hot hot for 18. Its products are all created to give you more ways to use less, all designed to keep the things you love hotter or colder for longer.
The brand aspires to bring style, innovation and joy to sustainable living. That means doing good, being good, to each other and the planet through the power of design and ingenuity. With the world’s resources being spent, S’well believes that something as simple as buying a beautiful reusable bottle or bowl can make a difference.
Corkcicle started with a question in 2010: How do you chill wine to the perfect drinking temperature, without the mess of an ice bucket? They answered that question with the innovative design of their first product, the Corkcicle Air in-bottle wine chiller, but there’s much more where that came from.
Their product offering has evolved to include canteens, tumblers, stemless wine cups, mugs, and more, all with a fashionable touch. Corkcicle thinks that style and sustainability shouldn’t be tradeoffs – in fact, the brand believes in creating products that enhance personal style while reducing personal impact on the planet, so you can feel good about making them part of your every day.
In 1913, inventor William Stanley Jr. fused vacuum insulation and the strength of steel in one portable bottle, thus inventing the all-steel vacuum bottle we know and love today. In the century since, his vacuum bottle evolved from concept to icon and has become an essential part of workdays, road trips and outdoor adventures.
The most sustainable products are the kind that never need to be thrown away or replaced. Stanley has created reusable, Built For Life™ products for over 100 years, reducing demand for disposable products that end up in waste and water streams. The iconic brand is built on invention, innovation and inspiration with a timeless spirit that complements your wild imagination.
Nalgene bottles are made in the USA, durable, and a classic companion to a wide range of outdoor activities. But did you know that these bottles were originally developed for usage in scientific labs? In 1949, chemist Emanuel Goldberg designed and optimized jars, bottles, test tubes, and Petri dishes that were shatterproof and lighter than glass.
But some labware scientists who were also into hiking discovered how great these lightweight, leak-proof bottles were for trips to the outdoors. With time, a movement to reduce waste in nature grew as well, and people started opting for Nalgene bottles instead of bringing cans or glass bottles on their adventures. Nalgene has thus evolved into a staple in the outdoor industry, whether you’re team narrow mouth or wide mouth.
