Hydro Flask is a brand of insulated drinkware and food containers known for its double-wall vacuum insulation and durable construction. It became a trend among Gen Z and millennials in the late 2010s, though it remains a popular choice for outdoor enthusiasts and daily use due to its performance.
Materials and technology
-
Construction: The drinkware is made from 18/8 food-grade stainless steel, which is resistant to corrosion and does not transfer flavors.
-
Insulation: Hydro Flask's signature TempShield™ technology uses double-wall vacuum insulation to maintain the temperature of beverages. This process removes the air between the bottle's two stainless steel walls to prevent heat transfer via convection and radiation. The result is that cold drinks stay cold for up to 24 hours and hot drinks stay hot for up to 12 hours.
-
Exterior: The outside of the bottle features a proprietary powder coating that provides a comfortable, slip-proof grip and added durability.
Safety: Hydro Flask products are certified to be BPA-free and lead-free. The company transitioned from a lead-based vacuum sealing process over a decade ago to ensure consumer safety.
