Monster Cooler

Q: What is it made out of?

They are made of a thermo rubber and they work very well. I really like the ones I have. They work on different size cans or bottles by the way you can configure it.

Q: Does this fit a 16oz monster can.

It will fit into the bottom part of the 2 part cooler can and bottle holder.

Q: Will it fit in a cup holder

Thank you for the question. It all depends on the size of the cup holder. The Monster Cooler adds some additional size to the bottle or can and may not fit in a standard cup holder. The good news is that it floats!
