These down quilts contain from 80 to 150 gr/m2 (3 to 5 oz./ m2) of down.
The first manufacturing stage of this product is to make a channelled empty case, which is later filled with down and quilted by Ferdown’s especially developed machinery.

When compared with other systems, ours is a much safer and faster system and avoids stitching or compressing the down when quilted.
