      Rated 5 out of 5 by from LOVE IT I love Hydro flasks there amazing. They keep stuff cold and hot for ever.

      Rated 5 out of 5 by from Perfect for School Aged Kids Goes to school with ice and comes back with ice, perfect for keeping water cold in our Texas heat. They are also very easy to clean, and the hard plastic mouthpiece holds up to my kids chewing. I had some concerns about leaking after reading some of the reviews, but when closed properly we don’t have any leaking. Like all water bottles with a mouth spout it will leak when open, so you’ve got to make sure your kids close them before throwing them in their backpack or something. We’ve dropped it a couple times and they hold up well, like our other hydroflasks. We tried many different water bottles and these are our favs.

    • If I bought the 12oz kids bottle could I use the wide mouth flex cap from my 32oz wide mouth on it? Would that then make it ok for hot liquids and essentially "leak proof"? Would it fit as well on either bottle?

      Asked by: moreorlessd
      Yes the Wide Flex Cap does fit the Wide Mouth 12 oz Kids bottle.

      Is there any way to purchase the small grey vent stopper by itself? Ours has gone missing either in transportation or the dishwasher and now it really doesn’t keep water in the cup.

      For the the 12oz Kids Wide Mouth can I use it for milk? I thought I read somewhere that you are not supposed to put milk in a Hydro Flask.

      Asked by: Coleys005
      Yes, milk should be fine! We would just suggest taking extra care with cleaning after putting anything besides water in the flask.

      Are these kids straw bottles leak proof or resistant?  Do the bottles contain lead or have a lead dot at the bottom? Does the paint contain lead or expose lead if chipped?  Can they be washed in the dishwasher? If not what is the risk if they are

      Asked by: KElseyB
      None of our caps are advertised as leak proof. The flasks do not contain lead. We do not recommend putting the flasks in the dishwasher, it could cause them to lose their insulation abilities. If they are put in the dishwasher, it will void the warranty.

    1. Torso Measurement

      • Bring your chin to your chest and feel for the most prominent bony bump where the slope of your shoulders meets the back of your neck. This is your C7 vertebra, and the top of your torso measurement.

      • On each side of your body, feel for the top of your hip bones, just below the sides of your ribs. With fingers pointing forward and thumbs pointing backward, draw an imaginary line between your thumbs. This is the bottom of your torso measurement.

      • Stand up straight and have a friend with flexible measuring tape measure the distance between your C7 vertebra and the imaginary line between your thumbs. That’s your torso measurement. If you are between pack sizes, go with the smaller size.

    2. Hip Measurement

      While your torso measurement is the best indicator of your pack size, it’s still important to check your hip size when using a hipbelt. To find your hip measurement, wrap a flexible tape measure around the top of your hip bones, just below the sides of your ribs. This measurement is slightly higher than your waistline
