Up here in Ontario we have already experienced -20 Celcius at Altitude and Ice Pellets. Gloves are always a discussion around the DZ. I have about 6 differant types of Gloves and keep looking for more. You try a pair out and discover what characteristics are good and which are not in the Cold Temps.Some seem good on the ground,but become more slippery when they are colder at Altitude.
I have a Neoprene pair as well. They are exstremely warm , but they make your Hand sweat if you keep them on during the climb and it takes along time for them to dry out. So sometimes they may only be good for 1 or 2 jumps before they are to wet and Cold to wear comfortably.
Having Grip at the Fingers is very important for hanging onto a Wingstrut or Climbout Bars of larger Aircraft. You will not fel like you are losing grip.It may also help with your Grip on the Hackey at pull time, and your Handles at a Crucial time when EP's are needed.
Some of the Mechanic Gloves do quite well and have thinsulate.
Whichever gloves you cose to use always pratice your EP's several Times with them on before climbing onto a Plane and on the way to Altitude.
