Blankets are lightweight and used on the bed generally for spring or summer. Blankets normally feature smaller quilted boxes that vary from 8 inches to 10 inches. Down bedding products are available in an array of weights, qualities, colors, and sizes for a cool sleep or one that will warm you from the chilliest of night winds. Because down is so lightweight, it is one of the most comfortable and preferred fills for a blanket or comforter.
A down blanket resembles a thick, feathery quilt, but is filled with down feathers from geese or duck. Down is astonishingly light, soft, warm and luxurious, making the down blanket an extremely popular bed covering.
Nearly all feathers lay flat with a central quill, but true down do not have a hard shaft and the feathery filaments are "bushy" in form. This is what makes down so soft. It also gives it the capability to hold in body heat while letting moisture to escape —- a sought-after property known as wicking.
A down blanket will normally be labeled for its fill power. This rating indicates the quality of the down itself. When washed and sterilized, an ounce of down is measured to find out the space it occupies in cubic inches. Very pricey down might have a fill rating of over 700 cubic inches, while a lesser quality down will be closer to 300, but the average down blanket will have a rating of about 500 or so. The higher the rating, the fluffier the blanket, and the more warmth it will provide.
One more rating is fill weight, which is a amount of the actual bulk weight used in the blanket rather than a description of the quality of the down
In order for down to stay uniformly spread throughout the down blanket, either baffle boxing or sewn-through stitching is used. The latter is less costly and creates a quilt-like appearance of "pockets" that hold the down in place. Nevertheless, because the stitching goes through from top to bottom, these blankets do not insulate as well and will not be as fluffy.
A baffle refers to material inside the blanket that runs upright from top to bottom, creating 'boxes' that hold the down into hefty inner compartments at the same time permitting it to stay fluffy. Even here some baffle boxes are not completely sealed and down can shift over time. For this reason the consumer may want to look for true baffle box, occasionally called end-to-end or closed baffle.
Even if down clusters seem soft and fluffy, they are able to leak through any fabric that holds them. It's imperative to purchase a cover with a high thread count, tightly woven, providing leak proof coverage. Then you won't have to be concerned that the down or feathers will sneak out. A lot of companies take exceptional care to seal in the edges, too.
