This is a good way to get frost bite…. I do NOT recommend wearing a non-breathable layer next to your skin. (Sincerely, Your local neighbourhood backcountry medic…)
Thanks, I was thinking the same thing. I’ve heard/seen/read several other people doing the rubber glove thing as a first layer like the OP. I was also just thinking about last night when I was working on my bikes with latex gloves on, and my hands were soaked after about an hour. I feel like that would be uncomfortable during a ride.
I did some googling on the phrase “vapor barrier rubber gloves”, and the first article I found says don’t do it because of frostbite. To be fair, he’s an explorer in extreme polar conditions.

I often use plastic bags (or cut-in-half Amazon shipping/cushioning pillows) over my feet, but always over my socks and not next to my skin.
