What Makes a Great Insulated Water Bottle

The term “insulated” is a common one when discussing modern water bottle options. But what exactly does it mean? Technically, an insulated water bottle is one that incorporates an insulating material or construction that helps to prevent heat transfer between the inside and the outside of the bottle.

That is a pretty liberal interpretation that includes just about every water bottle out there. However, all “insulated” water bottles are not created equal.

Types of Insulated Water Bottles

Today’s line-up of water bottles consists of containers made from a wide range of materials. Knowing the advantages and disadvantages of each type will help you find a water bottle that makes you happy. Here is a summary of some of the common types of insulated water bottles to help you decide.

  • Vacuum Insulated. If you want to keep your water, iced latte, or favorite smoothie super cold for an entire day, this is the type of insulated bottle for the job. With a built-in vacuum chamber, not only will your beverage stay frosty cold, but you don’t have to worry about condensation forming on the outside of your bottle. The one major drawback to this type of water bottle is the weight. The double wall construction often makes them heavy.
  • Glass. If you want to go old-school and eliminate plastic, BPA, chemical leaching, and the nasty metallic taste some water bottles are guilty of, then glass is the way to go. Most are covered with a silicone sleeve designed to protect the bottle from cracking or shattering as well as providing extra insulation. They don’t work as well as a vacuum-insulated bottle when it comes to keeping water cold, but many consumers prefer the taste of water from a glass bottle.
  • Stainless Steel. Water bottles made from stainless steel are surprisingly lightweight. They are also, inexpensive, non-reactive, and BPA-free. They don’t always keep your beverage cold for extended periods of time, however so look for one that also incorporates vacuum insulation.
  • Plastic. A favorite of athletes and gym-goers, plastic water bottles often feature convenient flip-top lids for easy one-handed drinking. Be sure to look for a version made from a material that is BPA-free. Most plastic water bottles do emit a plastic-y smell and can alter the flavor of your water.
