Kept my hands toasty warm on a long walk on a very cold day! I have no other gloves that I can say this about, including my ski mittens. Because these gloves have a built-in liner, you need to take care when putting your hands in to make sure that the fingers go all the way in, but once they’re on, they are nice and warm. And being able to use the fingers to manipulate a screen is also very helpful. I highly recommend.
