I think the only time that neo gloves can keep me warm is if I'm rowing the boat. If I'm not generating body heat they are like mini refrigerators on my hands. I really like the wool fingerless, and once had a pair that were thinsulate lined that were great. I can't find them anymore. The fingerless wool with the hooded pullover mitten are real warm but also cumbersome as I have had the slack line from my reel get entangled in the hood while it was pulled back at a very unoppertunistic time.... frown
