I use these as a liner for my leather gloves and my skiing mitts. They're perfect as an insulating layer as my hands never, ever get cold. By themselves they're adequate in near-freezing or sub-freezing temperatures to pop open the ski rack or scrape the windshield, but I'm not sure I'd go very long with just these on my hands in temps like that. To be expected with any liner the grip is a bit slippery, but that's a minor quibble. I could actually unlock and use my smartphone with these on and that was an unexpected surprise. Results may very depending on your phone, but that's a plus in my book. Liked them so much I got a pair for my son to use too.
