Description
The wide mouth Nalgene bottles are not easy to drink from when on the move. Simply place this stopper into the top of your Nalgene and enjoy the convenience of a smaller opening to drink from on the move.
EDIT: The original design would get wedged very tightly (to the point of not being able to remove it) so I made the new design a bit smaller. Should work better now!
