After some research I bought this to combat the polar vortex -40 actual temperature. They work so well my hands could get sweaty shoveling snow. The pads on the back are pretty much useless as snow gets stuck in them quickly, but I wasn't planning on using them anyway. They don't fit over the sleeves of the parkas but I haven't had that problem at all and my larger than average arms fit well without being too tight. Overall, these gloves have more than proven themselves.
