What are the Similarities between Iron Flask and Hydro Flask?
Image Source: Hydro Flask
The Iron Flask and Hydro Flask are covered in a special powder coating on the bottle’s exterior. So, what does this coating do? To put it simply, it increases the bottle’s durability. If either brand of water bottle falls out of your hand, the impact of the fall will be absorbed by the powder coating. This also emphasizes another great feature of this coating, a better grip. A steady grip is essential for high-intensity activities such as climbing or trail running.
The powder coating also provides many colors for these popular water bottles. For example, you can purchase the Iron Flask in 24 different colors. The Hydro Flask doesn’t have quite that many options, but you still have 16 colors to choose from.
The stainless-steel construction of the Hydro Flask and Iron Flask water bottles significantly impacts their durability. Because of this, both brands are incredibly sturdy. In addition, stainless steel bottles can absorb a lot of impact from a fall, as long as they’re not dropped from a high height.
Even better, both brands of water bottles are made from a particular type of stainless steel: 18/8 pro-grade stainless steel. This variety makes both the Hydro Flask and Iron Flask easy to clean. It also helps keep the taste of your hot or cold drinks as pure as possible.
Iron Flask and Hydro Flask water bottles are well-known for their insulation qualities. This is very useful in both the hot and cold months. Are you heading out on a winter backpacking trip? An Iron Flask or Hydro Flask is a great companion to keep you both hydrated and warm.
Iron Flasks are designed to keep your hot drinks at the same temperature for up to 12 hours. Hydro Flasks are supposed to do the same thing, but many users report hot beverages only staying hot for 8 hours.
Or maybe you’re planning a long bike ride in the summer heat. These well-insulated water bottles are just as beneficial to keeping your beverages ice-cold all day long. Both Iron Flask and Hydro Flask water bottles are designed to keep drinks at cold temperatures for up to 24 hours.
The Biggest Differences Between Iron and Hydro Flasks
How They Look
Both brands of water bottles have similar physical characteristics. Since they both have powder-coated exteriors, the look and feel of these bottles are alike. There are some key differences, though.
The Iron Flask comes in a wider variety of sizes and colors. Each Iron Flask bottle also comes with three different lids: a straw lid, a flip lid, and a regular stainless-steel lid.
While Hydro Flasks may not have as many options for lid styles and colors, it has one important feature- a leak-proof cap.
One big difference between the two brands is how many size options are available. The Iron Flask is available in six sizes: 64oz, 40oz, 32oz, 22oz, 18oz, and 14oz. However, the Hydro Flask is only available in three sizes: 24oz, 21oz, and 18oz.
The 18oz Hydro Flask weighs 11.3 ounces, whereas the 18oz Iron Flask weighs about 18.5 ounces. When thinking about carrying weight on any outdoor adventure, that’s a pretty considerable difference.
How long do liquids stay warm and cold?
According to Iron Flask, their water bottle can keep hot drinks hot for about 12 hours. However, many consumers report that beverages start losing their temperature well after that 12-hour mark.
In comparison, the Hydro Flask water bottle is also supposed to maintain the temperature of hot beverages for about 12 hours. But many consumers report that this bottle can’t keep a drink hot for more than 8 hours.
When it comes to cold beverages, the Iron Flask can keep your drink cold for up to 24 hours. This comes in handy when you’re embarking on a full-day hike at the peak of the summer. Once your bottle is filled, you’ll have icy cold water all day!
The double-walled Hydro Flask can also keep beverages cold for a long time. Like the Iron Flask, it can keep drinks cold for up to 24 hours. However, some consumers have reported that the Hydro Flask water bottle can’t hold water cold for as long.
So, the Iron Flask comes out on top with consistency when it comes to keeping liquids at their desired temperature.
Dishwasher vs. Not-Dishwasher Safe
In general, dishwasher-safe water bottles are more desirable because it’s easy and efficient to wash them. The Hydro Flask is a dishwasher-safe water bottle and, therefore, extremely easy to clean. Just toss it in with the rest of your dirty dishes, and that’s it!
In contrast, the Iron Flask requires handwashing with soapy, warm water. It’s not a complicated task, but it still needs more thought and work than the Hydro Flask.
The most differentiating feature of these vacuum-insulated bottles is the price. If you’re looking for an affordable option, your best bet is to go with the Iron Flask. Additionally, the Iron Flask comes in a wider variety of sizes that can fluctuate the price.
On Amazon, the 22-ounce Iron Flask is $22, and the 64-ounce version is $35.
So, if you’re looking for the cheaper option, your best bet is to go with an Iron Flask.
