I've seen/used the clear vinyl gloves quite a bit as they are common where I work. If they were to work as an overglove they would have to be very large unless the user has small hands or is using very thin liner gloves. Durability would be an issue. They stretch a little bit but they are also easy to tear. They are a one use item at work and the same would probably hold true in the field.
We also issue a clear
polyethelene glove which is cheaper but even less durable. I would reserve this glove for emergency use only.
There are also latex rubber gloves out there but they would have to stretch pretty far to be used as an overglove.
All of the above gloves make my hands sweaty pretty quickly and that's when I'm not even moving very much. The powdered versions can also be messy.
