    Cold, heavy water
    This water bottle keeps liquid super cold. I only wish it was lighter. Dropped it at the gym and everyone turned to look - it is that heavy.

    We have FIVE Hydro flasks that we use for the whole family. Three of us worked at camp all summer 2018 in the really nasty hot and humid weather; two outdoors the majority of the day and one in/out of doors. Our water was kept very cold thankfully. Yes, one flask did incur minor dents and slight paint chipping on the bottom edges with accidental dropping. This did not compromise the integrity of the flask and was irrelevant for us with the hard day-to-day useage for eight long HOT weeks. Post camp three of the flasks have now gone off to college for the collegiate soccer season where they will be used for preseason daily double work outs followed by a rigorous fall playing schedule. With our active lifestyle (swimming, golf and tennis), we will continue to enjoy the benefits of COLD water in our hydro flasks for all our athletic endeavors. Great product!
