Since we have been evaluating water bottles, travel mugs, and other beverage containers for four years, customers often ask us to provide a comparison between YETI and hydro flask customizable. Although YETI’s insulated tumblers are still well recognised, we put the more recent insulated Rambler water bottle and the well-known Hydro Flask to the test to see which of these companies invests more in their insulation engineering. We also tested a lesser known Klean Kanteen bottle with a narrow neck. This bottle did better in insulation tests because it had a narrower aperture that allowed less heat to enter or exit. Some of our testers also liked it since they thought it was simpler to drink from.
The Test Using Cold Water
After filling it with water, we poured around 4 pounds of ice from a convenient portable ice maker into a large stockpot. We allow the ice to melt since it absorbs more heat, and it isn’t easy to guarantee that more of that thermal capacity is not entering one container over another. Put as much ice that hasn’t already melted in a drink if you are genuinely attempting to keep it cold for 24 hours. Over 40 hours, we recorded the water’s temperature. The bottles were all exposed to the sun for almost an hour, and the temperature outside peaked at 94 degrees Fahrenheit. Lows during the night were approximately 73 °F.
In this test group, there are two controls: A wide-mouth bottle with an even bigger non-sealing cover than the YETI Rambler Insulated Tumbler, a stainless steel klean kanteen that is not insulated. As predicted, after only two hours, the bottle with no insulation tracks extremely near to ambient temperature.
The Klean Kanteen’s victory over the other insulated bottles was, therefore, no major surprise in light of prior testing. The tumbler is insulating well, but the vast, thin plastic top is undoubtedly a disadvantage when absorbing solar heat. The Hydro Flask, which begins to heat up substantially more than the other two bottles after the third hour, was the second surprise. The difference was roughly 7°F by the middle of the second day as opposed to less than 1°F between the first two.
Easy To Drink
Here is the test, which is much more arbitrary. There are three different methods to approach drinking from water bottles, which we have been studying since 2017. Since opening wide mouth water bottles is more like a cup and the top rim is less likely to contact your nose, some people prefer to drink from them. Others like a mouth that is smaller since it makes it easier to drink without worrying as much about leaking. Drinking from a spout is a third option; all of the water bottles we evaluated come with the choice of a spout or straw lid. It would be best if you drank much more slowly because of the spout, but it prevents spills on your shirt. A spout also prevents heat from pouring in every time you drink, which is helpful if you are attempting to maintain water ice cold over a hot day.
Cleaning
A decent kitchen scrubber will simplify cleaning a bottle with a broader opening. For two reasons, a vacuum insulated stainless steel bottle shouldn’t go in the dishwasher. The first is due to worries that soldered connections or plugs may be damaged if joints within the insulating sleeve are stretched by heat, which causes the metal to expand and shrink. The second worry is about the color coated surface becoming damaged. According to the company, all of YETI’s bottles are designed to withstand the heat of a dishwasher. Klean Kanteen and Hydro Flask advise against washing their insulated bottles in the dishwasher.
The Wide Mouth Hydro Flask
One of the market’s most well-known insulated water bottles, the Hydro Flask began as a small Oregon design team selling bottles in 2009. Finally, it developed a strong enough brand to fetch $210 million in sales in 2019. Despite diversifying into other insulation related product categories, Hydro Flask has maintained its focus on water bottles. Instagram users and Redditors are quite enthused by the company and their liberal replacement policy for things like damaged caps or even full bottles.
Pros
- Continual guarantee
- A massive range of sizes and colours
- Accessories are accessible due to their popularity.
Cons
- The performance of the insulation is merely mediocre.
- Not very narrow lid openings
- Not very broad lid apertures
