OK, my first answer is for this time of year here. When the water is still soft enough you can't drive the truck on it I go in stages. First the fingerless wool gloves. Then fingerless wool gloves with neoprenes under them. Neoprenes are not very good at keeping your hands warm, just dry. In between I sometimes use thinner gloves under the wool fingerless ones. I also hae a pair of fingerless wool ones that have a fold back mitten end that hooks to the back of the glove with velcro and they are insulated with thinsulate. I think a bunch of gloves will work better than a single pair.
