    Rated 5 out of 5 by from Perfect for what I need I ordered this Hydro Flask as a container for my Lactose Free milk at work. It's perfect. It's tipped over several times and it never leaks. I got the optional lid and I don't know if that was necessary but I'm happy with my purchase

    Rated 5 out of 5 by from Love this product!! I bought this for my son for Christmas. ( He said Mom, I want a Hydro Flask). He absolutely loves it. He brings it to school everyday for his water. It stays cold all day! So happy i bought it.

    Rated 5 out of 5 by from A life changer! Everyone on my gift list received a Hydro Flask this year after I received one as a gift over the summer. Now my daughters won't drink out of any other water bottle! I sent my brother a Coffee Hydro Flask and my husband got a second Hydro Flask after someone swiped his at work! The only negatives are they are a bit heavy and pricey -- but other than that, the design is perfect. My youngest asked for a "big" Hydro Flask to replace her kid one because "she is going to be 8 in five months!" A life-changing product!

    Rated 5 out of 5 by from If you like your liquids cold! I asked for this product for Christmas, and got it! I wanted it as my workout bottle, because I love my water as cold as possible. I could not be more pleased with how cold and for how long this bottle works. So I highly recommend it. Don’t forget to buy the sports top to go with it!

    Rated 5 out of 5 by from Awesome waterbottle for anyone I bought this for my parents who do not like using reusable waterbottles. They love them! Have been using them most days and claim it keeps their water so cold. Plus, they love the sleek design and crisp colors.
