I have tons of Hydro Flasks because you can't have too many. This one is my personal favorite because it's a great size and the straw top is awesome. Water stays cold for a long time no matter how hot it is outside and the design is cool and functional. This has also turned out to be one of my favorite things to give as a gift, people love it because it's not always something you would buy yourself but it's still practical. I highly recommend this product.
