Diving Dutch
Registered
I dive in a drysuit year-round, and find that in the winter when the water's around 35F, my hands get numb from the cold with 6mm gloves. Now, I wear Deep Sea 3-finger mitts. Like nkw5 writes, they are quite toasty, especially if you squirt a little hot water in them before the dive. Sure you loose a little dexterity, but it's better loosing feeling in all ten fingers.
