I love them both! I mentioned in my profile that my office is mostly white (and often compare to the Apple store), so something with some color would be nice. I didn't say what color, but my santa hit the nail on the head with this Nathan bottle. I love the green and coral combination. I work in ocean conservation and this bottle makes me think of the sea. The second bottle has an infuser so when I'm bored of plain water I can spice things up with some fruity flavored water. Thanks so much santa!
