64Hydro Stainless Steel Water Bottle Review

The 64Hydro is a stainless steel reusable water bottle which carries all the expected characteristics, such as the double-wall vacuum insulation (to keep your beverages hot or cold), a solid construction and the BPA-free plastic cap. But, unlike some of its competitors, 64Hydro has delved a bit into the water tracking realm which is currently dominated by the smart water bottles (such as Hidrate Spark or LifeFuels, the latter offering vitamin-rich pods).

There is no intricate water intake tracking system or anything of the sorts but a simple time marker that’s printed on one side of the bottle to remind you when you should take a sip. I’m not entirely sure how effective it can be for those that forget to drink water, but I do think it would work far better with the transparent bottles (to actually see the remaining liquid), while on the stainless steel, it only enhances the aesthetic value of the water bottle.

The purpose of these reusable water bottle is mainly to be more eco-friendly especially considering that we got accustomed over the years to simply buy a bottle and then toss the plastic into the trashcan, but, surprisingly only a small percentage of those actually get recycled, while the rest ends up into the oceans. So, we can wait until the big corporations fix their own wrong ways or we can limit the amount of waste that we create by ourselves, making baby steps towards fixing our environment. And that’s where water bottles such as the one from 64Hydro come into play, offering the means to be more eco-friendly, while it doesn’t require you to make any compromises: the water bottle is stylish, it’s easy to use, easy to transport and keeps your water cold or hot.

That being said, the 64Hydro water bottle that I got available for test is 32oz (or a liter) and, when put next to the 16oz Noerden Liz, it’s clearly a larger container, but it shouldn’t take that much more space from you bag. And indeed, having a 3.5-inch diameter and being 9.8 inches tall (9.0 x 25.0 cm) ensures that the 64Hydro water bottle can be carried around quite easily and there’s also a loop built into the plastic lid that allows you to simply attach it to a traveling bag. Well, it’s clearly not really going to be the most lightweight object in your purse since when fully filled, it weighs about 2.8lbs (1.3kg) and, when empty, it weighs about 14 ounces, which is in line with another very popular bottle, the Hydro Flask.

The bottle that I currently use is black with a nice painting of a sunflower and butterflies (yes, there’s also a motivational quote :)), but, if you check the official website, you will see a huge amount of options to choose from, with various prints and colors (and I mean it, there seems to be hundreds to choose from). You can also go a step further and customize what’s written on the bottle (your name) for free. Besides the stainless steel bottle, there is also a fully transparent bottle available with built-in fruit infusion filter (the material used is Tritan co-polyester plastic), as well as a black water tracking bottle series (which is the same as the transparent one, only in a darker shade). The difference between the transparent (or semi-transparent) bottles and the stainless steel ones is mainly the lid which, in the case of the latter, it relies on a straw, making it more suitable for those people that like to practice outdoor sports and who are constantly on the run.

The straw and the lid are the only plastic parts of the bottle, so it’s important to know whether they’re safe to use over a long period of time. The good news is that the manufacturer used BPA-free Tritan co-polyester plastic and it’s also toxin-free to make sure that the water will not have a plastic taste or will acquire any weird odors (I assume that this means that it’s also phthalate-free, but I could not find any clear info in this regard). It’s worth mentioning that at the top of the lid, the mouthpiece is retractable and, while initially it may seem more rigid, the mechanism softened up after a couple of days. I know that a lot of you prefer a water bottle that has a larger opening since, this way, it’s easier to both add ice cubs and to clean the bottle, and yes, the 64Hydro does have a very wide mouth (it has a diameter of 2.55 inches or 6.5 cm).

This way, you can easily clean the container using a sponge or cloth and, to also thoroughly clean the straw, 64Hydro has added a very narrow brush inside the package. But is it dishwasher-safe? I found conflicting information on the official website since on the product page, the manufacturer says that the bottle can be washed in the dishwasher, but it recommends hand washing it with hot soapy water. At the same time, on the more general page, it’s clearly written that the 64Hydro 32oz bottle (the one that I got) is not to be used in a dishwasher at all. So, to be safe, just hand wash it every day with warm water and soap (non-abrasive); also don’t use bleach or chlorine since it can damage the bottle. Besides the stylish look and the easy-to-carry aspect, the 64Hydro prides itself with the double-wall vacuum insulation which should ensure that the hot beverages will remain hot for up to 12 hours, while the cold liquid will keep its low temperature for up 24 hours.

To test this claim, I filled the bottle with hot water (about 120 degrees F or 50 degrees C), closed the lid (which, by the way, is spill-proof) and checked the temperature of the water from time to time to see how long it will remain hot. The water remained relatively hot for about 6 hours and a half and then it gradually got warm (it remained mildly warm even after 24 hours have passed). As for cold water, I filled the bottle with ice and left it alone for about 24 hours – at this point, the ice was fully melted, but the water was still cold, so the claim was accurate.

Conclusion

64Hydro is a relatively new player in a very competitive market, but it can certainly hold its ground against its main competitors due to the solid construction of its water bottles, the reliable insulation and the artsy look. There is a huge variety of prints to choose from and I also have to mention the water intake reminders as an alternative to the notifications that you would get from the smart water bottles. So yes, the 64Hydro water bottle is functional, it’s stylish, it helps the environment and the price is right which makes it a great solution for those that want to remain hydrated throughout the day.
