In my previous job in Coast Guard Fleet I held the Research
& Development file for uniform clothing
. One of the problems we were working on was mittens and gloves for cold weather work
. The best choice for cold weather work
ended up to be the natural wool mittens with a durable leather outer liner. IIRC the wool was the quicker to wick moisture away from the skin and dry faster as well. The guys working on the decks retrieving/laying buoys in -20 deg C temps would keep 3 or 4 pair on the drying racks at all times.
The high-tech gloves that the guys liked were something like what Scully & Weyalan described. They were a polypropylene inner liner with Thinsulate insulation
and a Goretex outer shell. They weren't as durable as the natural hide outerliners but for guys that needed more dexterity they were superior. If you're not going to be needing that type of cold protection I would think a divers "swim skin" type of glove would work well. A few guys (myself included) would use them inside our warmer mitts.
