Down sleeping bags usually have a better warmth to weight ratio than their synthetic counterparts - so long as you don't get them damp. Performance varies according to the quality and fill power of the down - the higher the fill power, the warmer it is. Also, choose between stitch-through construction and baffle wall construction, between different shapes of bag, and a wide array of fabrics.
