      Rated 5 out of 5 by from Wonderful Bottle I have owned a Hydro Flash before and just loved it, but wanted to change colors. The feature that I think is best about Hydro Flash is it doesn't leak and the ice I put in stays ice for up to 19 hours.

    • Can these be put in the dish washer?

      Asked by: Swiftie26
      No, I would not recommend it. If you put it in the dishwasher it won't be able to keep water cold/hot.

      Is it leakproof? Could I throw it in a bag and not worry about leakage?

      Asked by: Maria 1475
      The Flex Cap is leak-proof. That is our only leak-proof cap.

      do these get banged up pretty easily? like if i get a white hydro flask will it stay white or get scuffed and ruined easily?

      Asked by: hannah1eigh
      The flasks are durable, but they are not indestructible. If you wash it regularly, it will stay white.

      Can you buy just the water bottle without the lid?

      Asked by: Grace1827317
      We only have two flasks available right now that come without lids. They are the True Pints and the Cooler Cups.

      Stickers will fit on the Wide Mouth 18-Ounce flask, depending on the size of the stickers.

      What are the height dimensions for the 18 oz wide and standard mouth bottles?

      Product dimensions can be found on our FAQ page. You can see them here: http://www.hydroflask.com/frequently-asked-questions/

      Someone asked about the difference of coffee flask vs regular hydroflask and customer service answered nothing but the cap. But the description says the coffee flask keeps hot beverages hot for 6 hrs and hydroflask keeps it hot for 12 hrs, so which is it?

      Asked by: Moonpie
      The flasks are the same. The difference is in the cap. The hydration flask has a better insulating cap in the flex cap, which is what gives the time difference.
