From my windsurfing / Kiting days in Wellington we were cheap skates and used dish washing gloves as they kept the wind chill off and you can grip, as I have had problems with sore hands with neoprene gloves as they slightly spread fingers while holding boom / bar so hard to grip
Choice for the cold here is 1.5 xcel infinity vs fcs 2mm
My guess is the infinity will be warmer than fcs due to the quality and lining .
3mm may be just to bulky for sup
