Reviews of the Best Insulated Water Bottles of 2020

There are not actually more insulated water bottles than there are stars in the sky, it just seems like it when you are trying to decide which one to get. Our goal here is to narrow down for you at least which features to check out, if not find the best insulated water bottle for you.

Many people are using an insulated water bottle to carry fresh, clean water with them somewhere that there is not an easy supply of water for them to tap into. Other people use an insulated water bottle more as a method to monitor water intake. Knowing how many refills are necessary in a day to achieve your hydration goals gives you an excellent way to use an insulated water bottle. Others use them to carry their morning coffee hot and fresh.

The insulation is designed to keep cold beverages cold and hot beverages hot. Cold water often has fruit or herbs added to make infusions. The water bottle will need to have a wide mouth to accommodate those. For those who use essential oils instead of fruit or herbs, a narrow mouth insulated water bottle will be fine. Hot water often has herbs or tea bags added as well. Again, the wide mouth is important. If you add only a powder, or prepare your hot beverage before putting it into your insulated water bottle the narrow mouth will work just fine, too.
