Excellent quality 10.5 tog duck feather and down summer quilt. The down is the feathers from the belly of the duck, this means it is softer and much more insulating making these excellent summer duvets. The feather and down also make these duvets light and lofty, giving you a comfortable and cool sleep. These duvets are also pocket stitched to hold feathers in place (Cheaper duvets won't be pocket stitched, which results in all the filling at one end). 85% duck feather 15% duck down. The 100% cotton cover made from super soft 220 thread count cotton makes this an all round durable duvet made from natural materials. Duvet sizes: Double duvet (200x200cm), king size (220x230cm) and 2 pillowcases (50x75cm), super king size (220x260cm) and 2 pillowcases (50x75cm)
