What Are We Looking For?

While researching and reviewing the best water bottle for keeping drinks cold, we rated them on the following:

How Long Do Liquids Stay Cold?

  • As you read in the title, this article is directly related to the best water bottle for keeping drinks cold. In this article, we review water bottles that keep drinks cold for 24 and up to 36 hours!

How Are The Water Bottles Keeping Liquids Cold?

  • Companies are constantly reiterating their water bottle design to enhance performance. Some designs are better than others for keeping liquids cold. The most common design on the market today is the double-walled, vacuum insulated water bottle. Two walls, with a vacuum insulating layer in between, helps separate the surrounding climate from impacting the liquid temperature inside the water bottle.

Lid Design

  • Lid design plays a large role in keeping liquids inside a water bottle cold. The body of the water bottle is typically manufactured as one piece without any separations. This is so no heat transfer from air entering or exiting the water bottle can occur. The lid, however, is usually the one place where air can enter or exit the water bottle, impacting the temperature inside.
  • While researching water bottle lids we looked at the following, which all impact heat transfer:
    • lid diameter vs. water bottle base diameter
    • lid type (straw, air-sealed, flip cap, etc.)

Considering all that was discussed above, our top 5 picks reviewed in this article include water bottles from (1) Hydro Flask, (2) HYDRO CELL, (3) YETI, (4) Simple Modern, and (5) Iron Flask.
