It is not a secret, that down does not warm itself – our body produces warm air, which down reliably keeps inside. It is possible because of down unique elastic behavior called Fill Power (FP).
However, in the modern world Fill Power cannot guarantee you quality. Popular today bird`s growth acceleration is effective in meat and eggs production, but harms down quality. Proper down selection requires own special laboratory, equipment and experts. Today in BASK Company Ltd. we have developed and patented our own technologies under trademark DSD®/DrySiberianDown®.
DSD® mark is used for every down, that passed BASK laboratory control. In order to keep down quality since 2021 BASK Company Ltd. production will contain composite insulators such as:
DSD® (original Russian down)
DSD® DWR (down with water-repellent saturation)
DSD® Pl (down combined with synthetic insulators)
DSD® Wl (down combined with wool)
