This is my third Hydro Flask, but my first 40oz water bottle. My other two are 20 oz. I was looking for something that I wouldn't have to refill quite as often because that takes time away from my breaks during the work day. I love the double wall insulation which keeps ice water cold the whole day! I also like the straw lid which easily lets me sip water, and has a little hole with which to carry the water bottle. It's easy to clean.
