The world embraced eco-friendly, vacuum-insulated bottles. Hydro Flask's standard lid has a honeycomb structure to help this insulation, and it's 100% leakproof, which I love because I can just throw the bottle in my bag.
Hydro Flask's great temperature retention is due to its TempShield technology. Two walls of stainless steel with a vacuum between prevent condensation and heat transfer to the outside of the bottle, keeping drinks hot or cold for hours on end.
if you're looking for a high-quality, colorful bottle that will keep your drinks hot and cold for hours, AND you want to blow up on VSCO, then Hydro Flask is the one for you.
