Where to Buy
The key to many of the virtues of Hydro Flask's zen lies in our patent pending, stainless steel, double wall insulated construction. By leaving a vacuum void between the interior and exterior walls of the bottles, liquids within are insulated from the elements without - hot or cold. Simple and extremely effective. Hot liquids stay steamy for 12 hours or more -even buried deep in glacial snow- while cold liquids stay refreshingly cool for at least 24 hours, long after the trail turns hot and dusty.
