My 4-year-old can't reliably close a bottle with a screw-on cap, but this one is easy for him to close & open again. That feature alone is a lifesaver when he calls "I'm thirsty!" from the backseat. And the lid is truly watertight. The quality is what I expect from Nalgene--that is, spectacular. And the designs are sweet.
