I note the back of the example illustration identifies the size of the rubber glove that the leather glove can be worn over. What is the correlation between rubber glove size and leather overglove size? Are they the same?

Hello,

The leather protectors are made to fit over the same size electrical glove that you pruchase. If you have a size 8 electrical glove, a size 8 leather protector would fit over that.
