Duvet is so warm, but we need a duvet insert in cold winter. Inserts can be everything such as goose and synthetic material. And, covers come in different weights and fabrics, and can be plain or quilted.
If you want to choose down-filled duvet inserts, temperature regulators, you should consider the percentage of down to feathers, and do not choose ones with a high percentage of feathers.
Besides, you should inquire about the fill power, for heavy fill power contains more fill.
It is recommended to choose down-filed insert which contains 100 percent cotton with a thread count of at least 230.
However, down-filed inserts are expensive. And it is difficult to clean down-filed inserts.
1. Synthetic Fibers
If you suffer from allergies, you can try hypoallergenic down alternative insert which is made of certain synthetic fabrics, such as polyester and other microfibers. When selecting hypoallergenic down alternative inserts, you should check their shell and the sewn-through construction which helps keep the fill in place. The shell contains at least 230 thread-count cambric cotton is the best choice for you.
But if you are allergic to polyester fiber filled duvet inserts, you should choose natural fiber inserts instead.
2. Natural Fibers
If you are more comfortable with natural fabrics, you can choose cotton, wool or silk.
- Cotton inserts will tend to cluster and “bunch up” after a while, making it lumpy. However, over time, cotton inserts may lose some softness and comfort.
- Wool-filled duvet can keep you warm during cold months and cool during hot seasons.
- Silk filled duvet could be the most high-end duvet, for natural silk prevents the skin from aging. Fine, smooth, soft, warm in winter and cool in summer, the silk protects the skin, promotes sleep, it is mite-resistant, antibacterial, absorbs moisture and release sweat; it is featured by excellent characteristics such as breathability, moisture absorption, humidity elimination, comfort, no static electricity etc.
