Luxurious 750+ FP goose feather and down with warmth, softness, superior resilience, and insulating properties, keeping you cozy and warm but not too hot all night. All-season weight is excellent for cold sleepers or cooler sleeping. This duvet is very light! A high loft down is incredibly insulating per ounce, but a little bit goes a long way! The longer you use them, the more comfortable and fluffy our luxury feather-down comfort will become, and the crunch of the actual feathers will disappear.
