How warm my hands are really tends to depend on my activity level. When I'm working hard, I need a lot less on my hands. When I'm driving, my hands tend to get cold easily.

I have not worn many of the high end gloves or mittens, but I can honestly say these Hestras are the warmest mittens I've worn. It would be nice to be able to reference a Marmot Expedition mitt or an OR Alti mitt for comparison, but it's not going to happen with the price of admission...
