In spite of their lack of dexterity, mittens are vastly superior to gloves. I have a pair of these TaylorMade mittens that I wear in cold weather while doing my (almost) daily three mile exercise walk. I found long ago that even much heavier gloves just don’t keep my fingers as warm as these (relatively) light mittens.
These are an excellent product that I highly recommend. If you play cart golf in winter weather, or do any sort of outdoor exercise, these are the bomb.
