I am no expert in MC heated gloves, but as far as I know, 8W minimum each glove would be better. 2A is already hitting the AA batteries pretty hard, so it would not be realistic to lower the heating element resistance (and increase the current drain and thus the power). Four AA batteries in series for each glove would give 4V which, with a 2 Ohm glove heating element, would generate 8W for each glove.

Quite right: all conductors (wire, connectors, switches, battery holder contacts, etc) between the batteries and heating element in the gloves must be sufficiently substantial to ensure that only an acceptable amount of power is lost. A 10% power loss should be acceptable, so the total resistance of all conductors, in this case, should not exceed 0.1 Ohms (with a 1 Ohm heating element). With care, this should be achievable.
