This is an awesome water bottle that started out as a Kickstarter project. My partner ordered two and they came in a couple of weeks ago. The Alex bottle is a metal water bottle that unscrews in the middle, making it super easy to clean! It also has a really sleek design and a rubber covering on the base to make it easy to hold. I highly recommend giving it a shot. You'll never need another water bottle!
