The longest I have ridden with the gloves was about 45 minutes at 35-37 F. At the end of the ride, my hands were very comfortable....not even a little cool. There was some wind...I would estimate about 8-10mph. I was traveling at an average speed of 30mph. I tend to avoid long rides in cold weather, at least until I get my new full helmet....the 3/4 helmet is a little cold on the chinny, chin, chin. By the way, the gloves were only $25 marked down from $60. I can't find any brand name on them, but they have Thinsulate 70 gram for insulation. Hope this helps.
