name contest

I need a name for the things I make. I use old bike tubes that are going to be thrown away....I turn them into cool jar covers. Many people drink out of jars and it is so much more convenient to have a jar with a strap or a mug handle on it! The material also offers a little cushion so the glass doesnt break.
In the picture you can see Jay has attached his 'mug style' jar holder to his belt.
Help me name these very cool jar holders!
If I choose a name you suggest, you win a custom jar holder!
