Cool Gear Dualwave 64 Oz. Gray Water Bottle

Want to drink the recommended amount of water per day in one container? Give this a try. My coworker and I bought these so that we will be encouraged to drink more water in a daily basis. Another coworker jumped in a purchase one too. A couple of issues I want to point out. 1) The top/cover doesn't screw on as easy, so you would have to fiddle around to make sure it get in right with the threads. 2) The straw is short, so you would need to open the top up to finish the small amount of water still left. The nice additional feature is the cool/ice pack that you can screw onto the top and is placed inside the bottle to keep your liquid cold/cool for consumption.
