They may cost a pretty penny compared to many standard water bottles, but Hydro Flasks are guaranteed for a lifetime, or 100 years, so you can purchase yours with complete confidence. They come in many sizes and lid designs, so you’re sure to find one suitable for a day at the office, a day hike, or a morning cup of coffee. Their insulated design keeps cold drinks chilled for 24 hours, and beverages like coffee, tea, and cocoa hot for up to six hours.
Joining the selection in today’s update is the 64-Ounce Wide Mouth, which conveniently can hold your full daily water intake, eliminating the need for refilling every couple of hours. Its wide mouth accommodates most backcountry water filters, so it’s a good choice for taking camping or on a day hike where you might need to fill it up again. Its cap features a flexible strap with stainless steel pivots, so it’ll move easily with you.
For a selection that’s certainly great for holding water – but also well suited for keeping carbonated drinks fresh – look to the Wide Mouth Growler, which comes in 32- or 64-ounce sizes and features double-wall vacuum insulation and rust-resistant materials. If you prefer a selection with a straw, you can’t go wrong with the Sport Cap S21ST001, which can easily be used one-handed and is great for use when you’re jogging or cycling.
A Brief History Of The Vacuum Insulated Bottle
Today, the company has expanded to offer a wide range of beverage containers and related products, all known for their durability and fun, eye-catching style.
Today, the name Hydro Flask has become virtually synonymous with vacuum sealed water bottles, but you may be surprised to learn the company didn’t actually invent the technology. That distinction goes to Sir James Dewar, a Scottish chemist. His 1892 invention was used in scientific applications, not for beverages; it wasn’t until 1904 that these flasks found their way into the hands of consumers. While you probably haven’t heard of Dewar, you’ve likely heard of this first commercial product, the Thermos.
Sadly, Dewar didn’t patent his idea, and the creators of the Thermos, German glassblowers Reinhold Burger and Albert Aschenbrenner, were able to profit off the technology without paying Dewar anything. And profit they did, as it didn’t take long for their version to become popular in Europe and, soon after, in America. The brand remains well known to this day, but over the years, plenty of competition has entered the scene, including from Hydro Flask.
The creators of Hydro Flask, then-couple Travis Rosbach and Cindy Morse, founded their company in 2009 with a mission: to make outdoor-use water bottles that could actually keep their contents cold. Until this time, stylish vacuum flasks for cold drinks weren’t as widespread, so their ingenuity came from recognizing that the technology had much more to offer. Despite issues along the way, including the breakup of the couple and a manufacturing crisis in 2012-2013, the company succeeded in fulfilling their mission with the original Hydro Flask bottle, which can keep ice water chilled for up to 24 hours.
Today, the company has expanded to offer a wide range of beverage containers and related products, all known for their durability and fun, eye-catching style. They’re popular with everyone from college students to outdoor enthusiasts, and for beverages including beer, coffee, wine, and more. While Hydro Flask earns a lot of love because it makes quality products, users also appreciate the lifetime warranty, which generally offers a replacement if a bottle’s vacuum seal fails. Not all companies stand behind their products this way, so for most users, a Hydro Flask lives up to the hype.
Cleaning And Care
There’s a common misconception that if you put only water in a bottle, it doesn’t need to be washed. After all, water is clean, right? The issue isn’t the water, however, but your mouth, which is teeming with all kinds of bacteria, both good and bad. When such bacteria take up residence on your Hydro Flask and lid, they creates unhygienic conditions and odors, and could even contribute to mold growth. Some experts have noted that using an unwashed water bottle is like drinking from a dog’s water dish or even a toilet. That’s why most health experts agree that you need to wash your water bottle at least once a day.
After five minutes, feel the outside; if there are any hot spots, the insulation is compromised and you should seek a replacement.
For a proper cleaning, you should use a high-quality bottle brush and skip the dishwasher, since the heat can damage or discolor a Hydro Flask’s powder coat. It’s not a good idea to soak the bottle in hot water, either, for the same reason. Instead, cleanse the bottle and lid thoroughly with warm, soapy water. If you notice any interior stains, you can try scrubbing it with distilled white vinegar or two to three tablespoons of baking soda dissolved in warm water. But never use bleach, as it can harm the stainless steel interior.
Once your bottle is clean and ready for service, you might be tempted to throw it in the freezer or put it on the stove to make your drink colder or hotter faster. Because of the vacuum insulation, neither of these actions will work, and the stove could actually damage your Hydro Flask. Instead, use ice cubes or heat your drink thoroughly before you put it in the bottle.
And if you notice that your beverage isn’t staying hot or cold like it used to, you may want to check the insulation. To do so, carefully pour boiling water all the way to the top of the vessel, then let it sit without the lid. After five minutes, feel the outside; if there are any hot spots, the insulation is compromised and you should seek a replacement.
Reusable Bottle Benefits
Every single minute, one million plastic bottles are sold around the world, and that amount is only predicted to grow. In fact, by 2021, consumption could reach half a trillion bottles annually. This creates a truly staggering amount of pollution, since not even a third of these are recycled, meaning they will live out their 500-year lifespan in landfills and the ocean. You can stop contributing to this form of trash by using a Hydro Flask or other water bottle, but becoming eco-friendly won’t be the only benefit.
A Hydro Flask, in particular, is fun and trendy, coming in a range of colors and styles for the serious, the funky, and everyone between.
For instance, by toting a bottle, you’ll stay better hydrated, because you’re likely to drink more when you have fresh, cold water at hand. But don’t worry if you aren’t drinking eight glasses a day, a suggestion that is more myth than actual scientific conclusion. Instead, drink when you’re thirsty, and take in a little extra if you’ll be doing any strenuous, sweaty activities.
Using a Hydro Flask could be good for your health in another way, too, since the water you consume isn’t sitting in plastic. Disposable water bottles, even those claiming to be BPA-free, have been shown to introduce chemicals and micro-plastics into the beverage, especially when exposed to high heat. Whether this is harmful and to what degree is under debate, but for most consumers, the idea of drinking plastic is not pleasant.
Finally, although it might seem a little shallow, it’s hard to deny that reusable bottles are the more stylish choice. A Hydro Flask, in particular, is fun and trendy, coming in a range of colors and styles for the serious, the funky, and everyone between. Many people slap stickers on the outside, to show off their personalities, and enjoy searching for and collecting retired colors.
