Fantastic!

I now have four of these caps because I love them so much. Such a simple piece of gear that saves you the headache of losing your bottle cap.

The new design is smaller and has a plastic O-ring. I appreciate the consistent improvement. If it's ever difficult to get on your bottle, just warm it up in the sun for a few minutes and it'll stretch easier.
