I own one of the larger Hydro Flasks, but bought this size as a gift for my sister in law. It’s perfect! She loves the size, which fits in both a cup holder and the water bottle pocket for her hiking pack. She also loves that it keeps her water nice and cold, which is my favorite feature! Also, they come in great colors!
I highly recommend this water bottle for both adults and bigger kids who are up to carrying and drinking larger amounts of water.
