I found a new water bottle, which I am actually really excited about. It is called the platypus plus bottle. It is a flexible plastic bottle (BPA free) which, when empty, will be completely flat. It is great for traveling because it takes up very little space and does not weight much at all. I am leaving for Hawaii on Friday and this will be a great resource for the trip. I can easily fill it up before boarding the plane, take it to the beach, the fitness center, and just have it with me to stay hydrated. I also like this water bottle because the water tastes really good and does not have a plastic-y taste to it.
