Wear minimal clothes inside your bag, like a dry base layer and dry socks. To be warm in your bag your body has to be able to breathe freely and circulate warm blood. Getting good circlation to your extremities is essential for staying warm. If your body is radiating heat, a good bag will retain that heat and reflect it back to your body. Your body and bag have to interact. Excess clothing can constrict breathing and circulation and interferes with that interaction.
