Okay so I have been able to survive with 5mm lobster claw gloves up until this week. Today was a rough day, I was out for only 30 mins before I felt like I was holding ice cubes, had to cut the day short.

Does anyone know if there are gloves you can put on under your gloves to keep your hands warmer? Also the gloves never seem to want to stay beneath my wetsuit, so the water creeps in there as well. My hands are extremely susceptible to cold, so any advice would be great
