When testing the metal water bottles’ ability to maintain cooler internal temperatures, all six bottles weathered one of this country’s most trying environmental elements—the Florida sunshine. The temperature hovered at around 90°F all day. When experimenting with hot liquids, the bottles remained in the refrigerator, which is kept at a cool 37°F.
Each temperature measurement was taken via Thermapen® Mk4 Thermometer, which boasts "the world's best in speed and accuracy."
Each test was conducted over 24 hours, simulating an entire day in these conditions. Whether you are searching for a bottle to last you through the Alaskan winter or the southern summer, this experiment will provide you with the information needed to determine your ideal bottle.
Below are two charts, the first being the results of the experiment conducted in the hot environment, the second covering the results of the test conducted in the cold environment. The results are ordered from least effective to most effective.

As evident in the charts, the Hydroflask® Type Bottle prevails over the other metal water bottles in both tests. This, the S’well®, and the Twist Top Insulated Bottle were the top three finishers in both experiments, with slight variations in °F. PROMOrx.com provides two of the top three performing bottles, providing a less expensive alternative to less effective name brand bottles.
This final experiment proves that there exists a knock off metal water bottle as efficient, or more efficient than a name brand bottle in every environment.
These results are paralleled in the first and second part of this series.
In addition to saving marketing dollars, you can maximize your company's available branding space. Household name bottles allow you to print your business logo, but your company is required to share this marketing space with the water bottle companies’ logo. Click here for an example of logo space sharing on a metal tumbler.
If you choose a knock-off brand metal water bottle, your logo won’t have to compete with another. Your brand will be, singularly, front and center.
