Plastic water bottles have served us well, but now there’s no excuse to avoid getting one with vacuum insulation. They’re superior in every way, keeping your preferred drink warm or cold for several hours. And they’re eco-friendly, keeping plastic waste out of landfills. An insulated water bottle creates a buffer between your beverage and the external temperature, while the double-wall construction precludes condensation on the exterior. 

Modern adventurers, athletes, entrepreneurs, and everyone in between know that investing in a high-quality water bottle is one of the most logical purchases you can make. However, not all water bottles are created equally. Grabbing a vacuum-insulated canister will provide you with more benefits than its plastic counterpart. Take a look at the market and you’ll see a wave of insulated bottles all claiming to be superior to the rest. Luckily, we’ve done the hard work for you by sifting through all the options to create a guide to the best vacuum-insulated water bottles available.

Best Vacuum-Insulated Water Bottles

What To Look For

Water You Know

Size: The size of your water bottle will largely depend on your personal preference. The larger the capacity, the heavier the bottle will be. So if you’re commuting or going to the gym, you won’t want something that weighs more than it needs to. However, this will also determine how often you’ll need to fill up, so if you’re not in a place where you can fill up regularly, you might want to opt for something with more capacity. Likewise, keep in mind factors such as the bottle’s footprint, especially if it will take up space on your desk or be required to fit inside a cup holder.

Cap/Lid: Your activity of choice will determine the type of lid you’ll want on your bottle. For working out, you’ll want a narrow spout, which prevents you from taking in too much at once, which can lead to cramping. Likewise, if a spill were to happen, there’s a smaller exit point for the liquid to come out of. If you’re driving in a car, you might want a built-in straw to minimize spilling even further and make it easier to open up one-handed. If you’re traveling long distances and looking for a bottle to throw into your bag and preclude leaking altogether, you might want a basic open-mouth drinking spout with a solid twist cap.

Materials: The materials of your vacuum-insulated water bottle will almost always be stainless steel, which significantly improves and maximizes temperature retention. However, you’ll want to keep an eye out for 18/8 medical-grade stainless steel, which will obviate any metallic taste being imparted to your beverage.

Finish: While it may seem like more of a case of aesthetics, the finishing coat on your water bottle can help improve your grip in certain situations. Something like powder coating will make sure it doesn’t slip out of your sweaty hands in the gym or during rainy commutes.

Built on a simple design, yet one that’s remarkably thoughtful, the Wide-Mouth model continues to evolve over the years, featuring the proprietary Flex Cap system which utilizes an innovative honeycomb construction to keep the lid insulated up top. You can also swap out a sip cap for a straw cap depending on what your activity is. Likewise, these bottles are easy to carry with the durable, flexible strap.

Still updating its flagship bottle, Klean Kanteen offers its Insulated Mug 2.0 for just around $25, which is nearly half the price of the top-shelf options, yet with similar construction and performance.
