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 exact insulated water bottle that is right 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.

We began with the best insulated water bottles by looking at the features and reviews. We narrowed the field down from literally thousands to these ten. Our hope is these specific ten insulated water bottles will have the range of differences and features so it is possible for you to know what will be best for you.

Whether your insulated water bottle goes with you in the car, riding your bike, to the gym, or to your office, it’s important to get the right one.

Several different details make a difference, like some you can put ice into and others it is impossible. That’s a big difference in how frustrating it can be to own.

We will examine the bottles and compare them on specific criteria. We will examine:

  • The different kinds of insulation, and how long you can expect your cold beverages to stay cold and hot beverages to stay hot. The different kinds will have advantages and disadvantages.
  • The mouth width is significant for how it is used. This matters for putting things into it and getting things out of it. Choose the mouth width of the bottle based on your planned usage.
  • The features of the lid vary, too. We hope they all are leak proof, but we will see what the reviews say. Some can be used one handed, some take two hands. Some you have to turn the bottle upside down to drink from, and others you can sip like a straw. We’ll examine all of that.

We will look at the sizes that each bottle comes in. This is important for two reasons. First is about how much liquid it holds. If it is too small and won’t hold enough liquid for you to get to the next refill, then it won’t do. Too big to make it too heavy to carry when it is full and that’s not great, either. Second is the actual dimensions. Mostly that doesn’t matter, until you need to put it someplace like a car cup holder, or a lunch kit. Then it matters.

  • We will check other features like carry straps, and squeeze bottles and how well designed they are. A serious looking grey water bottle might be best in some places, but sometimes we need a splash of color and a beautiful design to cheer us up and keep us motivated. If a water bottle being well designed makes it easier to stay hydrated, then we all need one!

Let’s compare these insulated water bottles and see what’s up.

8. Best Jet Lid: LoliBuy Sports Water Bottle Insulated Water Bottle

Sports Insulated Water Bottle

View on Amazon

An insulated water bottle with adjustable flow rate, this  LoliBuy Insulated Sports Water Bottle is a great value.

Type – This LoliBuy Sports Insulated Water Bottle is manufactured from a proprietary blend of BPS-free and BPA-free polypropylene plastic. The Podium insulated water bottle makes it so you can just taste the flavor of your beverage, and not the plastic of the bottle.

The best feature of this bottle is the squeezable sides. You squeeze the bottle to increase the flow rate of the liquid. Ideal for sports enthusiasts who want a quick burst of water while on the move.

No drips and no messing with the bottle to try to get a drink out of the top. Terrific for biking, the gym and the office. These are much like those Gatorade squirt bottles, but these ones seal up so they won’t leak all over your stuff.

Wide or Narrow Mouth – The combination of the wide mouth opening for ease of adding ice, and the squirt bottle opening for drinking from the lid is the best of both worlds.

Features of the lid – The proprietary lid is the basis of the greatness of this insulated water bottle. The sides of the bottle can be squeezed but it is the lid that makes the flow and the seal really work.

The jet valve self seals so it delivers a high flow of water when you squeeze the bottle and seals back up when you let go. You drink quickly and easily with no splatters or spills. No need to use your teeth to get the lid open to get at your water. Just squeeze harder and the water comes out faster.

The lid is secure so there are no leaks while transporting, or even while shaking up your powder mix drinks.

Sizes – This LoliBuy Sports Insulated Water Bottle is available in a handy 24 ounce size

Other Features – This bottle is backed by the “Got your Bak” lifetime guarantee.

Sports caps can often get really gross with buildup when they are hard to clean. This system is great for easy drinking as was a easy cleaning.

I would especially recommend this bottle for children. They get too old for sippy cups but they need something to be sure they keep hydrated. They need something that they can’t break, spill or otherwise create havoc with their juice or water. They love to drink out of the jet lid and it is impossible to spill.
