Review on humangear capCap for Parents by Jim Shirodkar

This really makes Nalgene bottles what they should be. It gives you the best of both worlds - a narrow mouth that's easier to drink from and a wide mouth that's easy to fill. This lid made drinking easier and seriously helped me form the habit of staying hydrated throughout the day. The narrow cover has a bulge that fits into the ledge on the handle. This keeps the lid on the side while you drink and is a great feature. The handle itself is also sturdy and I carry the bottle by the handle every day. My only complaint is that the black isn't quite black. The narrow hat is black, the wide neck steel blue. This is disappointing because at the time of purchase the cap had lettering all black.
