Used these gloves on the way in to work this morning, and overall I would give them 4.5 stars out of 5. Keeping in mind that I have a Gerbing electric jacket liner, which helps to keep my core temp up, I can say that my hands never got past feeling even slightly cool, and the temp was down to 26 in some areas with an average of 30 degrees. I rode for about 45 minutes, with 1/3 of that time being stop and go in the city, and 2/3 being time on the highway at about 75 to 80 MPH. (The bike makes me go fast) I have the hand guards on the bike, so I am sure they also helped, but these gloves are better than any of the other ones I have used so far.
Yes, they are a little bulky, but they are cold weather gloves so that is to be expected. The gauntlet on them is HUGE, but that was OK for me since it made them easy to get over the arms of my Aerostich suit. I think these gloves are about as good as it gets, without going to electric gloves.
