The Fourth Element Xerotherm Gloves are great to keep your hands and fingers warm in and around the water.  You can wear them by themselves out of the water while kitting up and under dry gloves as a low bulk underglove for maximum dexterity and warmth.  

Silicone fingertips add extra grip and durability in key areas and the Xerotherm material is a fantastic warm and flexible material developed for NASA and used by Navy and Police diving teams as well as the FBI for its performance.
