The calm core of even the busiest bed, our all season down comforter is not a mere utilitarian filler. All of our down and feather products are sourced from a Responsible Down Standard (RSD) certified supplier. Baffle box construction eliminates those annoying cold spots for a sleep so dreamy, it will transport you to far away places. And all John Robshaw Down is oversized to fill the duvet cover end to end. No more fighting over the covers.
