What experts liked

It’s also not really that expensive – both sizes are under $30. When you take into consideration the quality of build and performance of this bottle, this easily becomes the best value for money you can get.

But if you’re not into the straw, reviewers also note there’s another open-spout cap. “I love that I have the option,” explains one customer who calls this water bottle a “serious value.” She also adds that it’s completely durable, because she’s dropped it a couple times on a cement floor and “it has survived every fall.”

What experts didn't like

One issue is the size variety; this bottle is only available in 24oz and 40oz.

An Overview On Insulated Water Bottles

An insulated water bottle is an excellent choice if you want to reduce single-use plastic waste. Insulated bottles not only are an eco-friendly option, but they also keep your beverage at the perfect temperature all day. Most insulated water bottles have thermos-like construction, which means they can ensure your drink maintains temperature for long periods of time. There is very little temperature transfer to the outer walls, so the bottle remains comfortable to hold. Plus, insulated bottles don’t get condensation either, so you don’t have to deal with any moisture on the outside of the bottle.

Most insulated water bottles are made out of stainless steel, which is a durable and safe option. There is no risk of breaking, cracking or denting because of how strong stainless steel is, so you don’t have to worry if you accidentally drop your water bottle. Stainless steel is also comparatively light, so your bottle will be easily portable.

The Insulated Water Bottle Buying Guide

  • The height and width of the bottle is an important buying factor. If you use your insulated water bottle in your car, ensure that the bottle fits nicely into your cup holders. If you like to place the bottle in the outer pockets of a backpack, ensure that the size works for you. The bottle should also be comfortable to hold in your hands without feeling bulky or awkward.
  • There are different types of lids for insulated water bottles. Screw-top lids are fairly common and easy to open and close. Some bottles have spout or nozzle lids, which can be limiting to drink from. Some water bottles actually come with multiple lid options so you can choose which works best for you. Having a lid that attaches to the bottle, even when open, is handy for keeping everything together. This way there is no chance of losing the lid.
  • Angled bottles look interesting, but keep in mind that they may be hard to clean if there is a pronounced bottleneck. Typically, straight-edge bottles are the easiest to clean and maintain.
  • Having a handle on the water bottle is key, especially if you usually have your hands full. A handle makes it easier to carry your insulated water bottle along with a number of other things. You can also use the handle to attach the bottle to a purse or backpack.
