I mostly wear padded gloves of various manufacture, but for really long rides, I prefer unpadded gloves. I think that might be because they're not as sweaty? As has been said, hand comfort is all about position and the location of the bars and hoods. I find increasing reach by a few cm. can help decreasing the vibration's force on the hands, simply because the arms are more hinged, it that makes any sense to you. That's assuming that your position already takes the weight off your hands. If your hands are pushing down on the bars, vibration will be more noticeable. They should be light on the bars. Look at the photos in the
Numb Hands post.
