The double wall insulation keeps cold drinks cold for more than 24 hours and hot drinks hot for at least 12 hours. The fact that these insulated water bottles are BPA free means chemicals will not leach into the drink.
Hydro Flask ran posts on social media boasting about its lead-free manufacturing process. Here's the irony: Hydro Flask used lead in its cups, too, until the company was called out by the exact same safety advocate. Lead's pretty bad for you. Minuscule amounts of the heavy metal can be toxic, especially for children.
Yes, it is safe to drink from a Hydro Flask.
Stainless steel bottles have a number of pros and cons. Typically, they last longer than glass or plastic because they are corrosion resistant, and do not leach chemicals when exposed to sun/heat. They are generally more expensive than plastic, as the cost to produce them is much higher due to being energy intensive.
Hydro Flask (no lead since 2013), another internet-famous water bottle company, stopped using lead solder more than 10 years ago. “By mid-2013, the lead was out of the Hydro Flask production process because the brand designed a proprietary sealant, TempShield," a Hydro Flask spokesperson says.
Hydro Flask products undergo extensive, rigorous testing through third-party, independent labs for lead, BPA, phthalates, and other potentially harmful chemicals. Our products are compliant with applicable, current PFAS regulations.
Our tests favored Hydro Flask (it's one of our winners, in fact). It has excellent cold retention and a convenient straw lid and it can fit in your car's cup holder easily. However, Yeti water bottles are also good—if you prefer that chug-style cap. And you'd be equally happy with its cold retention and durability.
Stainless steel water bottles are better for individuals of all ages. They're BPA-free and don't collect any odor or harmful bacteria. Glass bottles, on the other hand, are fragile and require a lot of care. If you're looking for a bottle for your kid, a stainless steel bottle is the way to go.
Hydro Flask stainless steel insulated water bottle PROS
No BPA or BPS. Duh. And, incredibly, that includes the plastic lids and straws. That's because BPAs and BPSs are used in polycarbonates and epoxy resins, neither of which are used in the manufacture of Hydro Flask lids or straws.
All YETI drinkware is crafted from 18/8 kitchen grade stainless steel and are BPA free, meaning they are not only absolutely safe to drink from, but are also puncture and rust resistant.
Hydro Cell can keep your drinks hot for about 8 hours and cold for 24 hours. So if you are planning to go for a day-long trip, you may want to bring an insulated stainless steel bottle with you.
If you want a water bottle that will keep your water truly cold for hours, Stanley is the brand for you. However, for a water bottle that can withstand bumps, bruises and being knocked over, you might want to invest in a Hydro Flask.
Correct grade selection and good practice will minimise the risk of any localised corrosion. Therefore there is practically no contamination of water in contact with stainless steel and equipment will last a long time.
In 2012, we moved away from what was at that the time the industry standard vacuum sealing process and toward an innovative process that sealed our bottles without the use of lead.
Avoiding microplastics in water
Instead, you can use stainless steel or glass bottles.
Metals such as iron, steel and aluminum can be toxic to humans. In contrast, titanium is completely non-toxic to both humans and animals, in part because it is corrosion resistant.
While the Hydro Flask stands up to it's claim for keeping liquid hot, it really shines by keeping liquid cool. After 12 hours there was a net temperature loss of less than one degree! Many people also use the Hydro Flask as a beer growler, it will not only keep the brew cold, but will also keep the carbonation intact.
✔️ Temperature Retention: When we tested Stanley and Yeti water bottles side by side, they provided nearly identical temperature retention over 24 hours — the Stanley kept water cooler by just one degree compared to the Yeti. ✔️ Price: They're also quite similar in price.
Its water bottles are stainless steel, manufactured mostly in China, and use double-wall vacuum insulation to help keep liquids cold or hot.
