I have 12V Gerbing Vanguard gloves and their heated jacket liner. The highest setting I have ever used for the jacket liner is 1-3 in under 30 degree weather and the jacket is toasty and warm. However, the gloves at the full setting have never felt warm. I can feel just the tiniest bit of warmth in the gloves at the highest setting, but nothing even close to jacket level. I use the dual controller and have looked at my cabling situation several times. Gerbing has been no help. The gloves are extremely well made and comfortable if I can just get some more heat. This is my second cold season with them without any change. Just trying to figure out if they should work to the level I expect or just to the level they currently perform.
