| duck down tender feather 40X |
Most of you know that inside the soft
pillow you use to sleep on
is filled with either cotton or, in
most cases, feathers. However,
please know that usually, these
feathers aren't the ordinary feathers you
find on the outer parts of birds.
The feathers birds contain on the
external layer are tough compared to the internal ones.
The internal feathers, also known as
down feathers, are very soft and
are used as an insulation against
cold weather (its main function) by trapping air.
Through this reason, many industries
use down feathers for jackets, pillows, sleeping bags, and much more.

Just additional information: Certain
birds, such as herons, have unique down feathers called
powder down which acts as a
water repellent by spreading powder over one's body.
(So there are two types of down
feathers).
