These are a great glove to use as a liner or running glove. Wore these running and at one point was worried my hands would get too warm, but they stayed the perfect temp - that was a 2 hour run that started in the 30's and ended in the mid-40's. Have also used them as a liner under my gloves on some cold mountain days (0-20 degrees) and they were great, not too bulky under mitts or gloves. They're not substantial enough to keep you warm by themselves on super cold days, and I wouldn't expect them to be, but if you're looking for a good running glove or an extra layer to back up your winter gloves then you'll be happy with these
These gloves must be for show, they are nice looking, but they don’t keep my hands warm at all. Socks have always been great, however, theses gloves are disappointing.
