Kapok is a soft natural fiber extracted from the seed pods of Kapok (Ceiba) tree which is found in Thailand and Indonesia.
Also known as silk cotton or java cotton, it is luxurious to the touch and has all the qualities of down (without the cruelty of feather gathering). The fiber is non toxic, odorless, resistant to rot, as well as being 100% natural and organic.
This kapok is harvested directly here in Thailand and in it's purest form, untreated and unbleached as you can tell by it's yellow color (whereas a cheaper treated kapok is often noticeably whiter in color).
