There is no such thing as really warm gloves. The trouble with really warm gloves is that they would be so bulky that you'd have to take them off to use your hands. You'd be better off with a pair of lighter gloves inside a pair of chopper mittens or one of those muffs. You could even slip a handwarmer packet into them if necessary. Slip your trigger hand mitten off when you have to. The glove will keep your hand warm long enough to shoot.
