I have always seen water bottles like this and have been intrigued. I absolutely love this water bottle. Knowing that it can hold 32 oz of water helps me to know how much I'm drinking during the day. I've noticed that I'm drinking so much more water Now that I have this water bottle. I don't know if it's because the water stays cool, it's the water bottle itself, the straw or just a mindset. My whole family keeps taking my water bottle during the day so I think I need to purchase one for each of them.
