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!

My new project

Although I have not written about my jar in a long time, I am still obsessed. I still use my jar everyday for my drinks. I use jars even more than ever.
It's still cool that lots of people use jars up here.
So many people use jars for drinks, there is actually a market for jar holders. My friends and fellow RRAT members make jar packers-which I will have to highlight in another blog...next time-
Stemming from their idea, I started making these jar holders. They are very cool. I get alot of comments. I am still making prototypes, but i have a few pre-orders.
Any ideas on cool names?
