Natural Insulation Material with 400 Years of History<\/h2>\n

[\/vc_column_text][vc_empty_space height=”5″][vc_column_text]Down is the warmest material among natural materials. According to historical records, humans have begun to use duck down and goose down as filling for winter clothing from the 1600s. Down has been loved by humans because of its lightness, excellent thermal insulation, and water repellency for the past 400 years. See the following for the features of down.[\/vc_column_text][vc_empty_space height=”20″][\/vc_column][\/vc_row][vc_row full_width=”stretch_row_content_no_spaces” css_animation=”element_from_bottom” type=”grid” padding_top=”40″ padding_bottom=”0″ transition_delay=”1″][vc_column width=”1\/2″][vc_empty_space height=”40″][vc_column_text]<\/p>\n

Compared to polyester-based filling, down generates a much smaller amount of waste and requires less energy for production and disposal.[\/vc_column_text][vc_empty_space height=”40″][\/vc_column][vc_column width=”1\/2″][vc_empty_space height=”40″][vc_column_text]<\/p>\n

Down of waterfowl that should keep their body heat warm in water or in extremely cold weather is the lightest and warmest natural filling material.[\/vc_column_text][vc_empty_space height=”40″][\/vc_column][\/vc_row][vc_row full_width=”stretch_row_content_no_spaces” css_animation=”element_from_bottom” type=”grid” transition_delay=”1″][vc_column width=”1\/2″][vc_empty_space height=”40″][vc_column_text]<\/p>\n

Down has outstanding air permeability which helps the body to maintain a constant temperature and provides a pleasant environment regardless of the exterior environment.[\/vc_column_text][vc_empty_space height=”40″][\/vc_column][vc_column width=”1\/2″][vc_empty_space height=”40″][vc_column_text]<\/p>\n

Thanks to this feature, down softly covers the human body with being transformed to fit the body curves.<\/p>\n

That is why down is widely used for winter clothing for outdoor activities and bedding.

The higher bulkiness is, the more air down can trap, and thus the higher thermal insulation and lighter it is.[\/vc_column_text][vc_empty_space height=”40″][\/vc_column][vc_column width=”1\/2″][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
