Vermont can get very cold in the winter. When the temps drop below zero degrees Fahrenheit, these mittens will still keep you warm. This was tested by my little girl on a -15 degree day. Her hands were toasty. So here is an adult version for all of us who love winter and all that it brings, but also love being warm and toasty. Go sled, ski, walk or dig in the snow bank with your kids. Yes, they will get covered with snow, but hey that is okay, you will still be warm.
