Hands down, the best insulated water bottle out there is from Klean Kanteen.

Klean Kanteen is known for being one of the most reliable, high quality water bottle brands, and their insulated water bottles are no exception. The Klean Kanteen Reflect at Amazon. 

An excellent insulated water bottle keeps its contents hot or cold for a long time, is nontoxic, and is easy to clean. This is all of those things.

I love the look and price of this bottle. Which makes it even easier to recommend. It comes in a variety of colors and sizes, and has many different kinds of caps that can fit it. You’re sure to find something that fits your needs. I thought I’d write this up to help other people see why this bottle is so great. 

Double-wall vacuum insulation

The most important part of an insulated water bottle is its ability to keep its contents (you guessed it) insulated. Whether you’re looking to keep iced water nice and cold, or to keep hot tea steaming all day, this water bottle has you covered.

It can keep your hot beverages warm for up to 20 hours, and cold beverages cold for up to 50 hours! Those are some pretty impressive timelines. Maybe you need hot coffee throughout a long day of errands. This water bottle will deliver.  It’s also an ideal bottle for camping or hiking. Even when you can’t re-cool your drink, you’ll have cold, refreshing water that will last for a long time.

Choose from the 12, 20, 32 or 64 ounce version at Amazon. 

Leak-proof cap

There’s nothing worse than a leaky water bottle. It can wreak havoc in a well-organized backpacking pack, or spill liquid over important class notes, or even cell phones and other electronics.

The leak-proof cap on this water bottle will prevent that from happening. Your belongings will stay nice and dry while you transport your beverages.

Large opening

The opening at the top of this insulated water bottle is larger than most bottles. At 1.75 inches (that’s 44mm), this bottle is easy to fill and pour from. You won’t need a funnel to refill it. You can relax knowing that it’s easier to clean too.

What customers are saying

People love this Klean Kanteen insulated water bottle. The reviews are overwhelmingly positive, with people using them to fit a variety of needs.

Kids and adults alike love the fun colors the water bottles come in, and people consistently say that they live up to the promise of keeping things warm or cold for extended periods of time.

They are durable, effective, and easy to clean. People simply love their purchase.

A few people mention receiving water bottles in colors that don’t seem to match the colors shown online, which isn’t great. The orange in particular doesn’t seem to look like the color they advertise. This is a fairly minor inconvenience. I still find it easy to recommend this insulated water bottle as a great purchase.
