Wamsutta Duvet Covers

Wool down and silk comforters are great for the top layer of your natural fiber bed.
Synthetic down comforters provide a cost savings over natural goose or duck down comforters, but a natural down comforter breathes more effectively than synthetic and provides more thermal warmth (it is usually more durable as well).
Most alternative down comforters are hypoallergenic (for those of you who are allergic).
Bed comforters are manufactured in a variety of fabric fibers.
Silk comforters are cool in the summer and warm in the winter.
Washing Tips for down comforters: Do not use bleach or fabric softener.
No down comforters have 100 percent down, 95 percent down is the highest percent fill on the market (with 5 percent or less feathers).
Ringed: Ringed comforters allow the down to shift throughout the duvet, and while the ring design may not provide consistent heat, it allows you to concentrate the down where you are the coldest.
Goose down comforters are made from the down of geese.
Regular laundry detergent can harm down comforters and bedding by breaking down its natural construction and loft.
Comforters with mostly feathers and a low percentage of down are still a good product and often low in price.
Down comforters are often categorized by fill power, or fluffiness, and weight (how many ounces of down are in the comforter).
The entire point of down comforters is, simply, to be comfortable.
