Pangaia's FLWRDWN jacket is A 100% recycled polyester shell with a flower down filling. ​FLWRDWN is​ a fully biodegradable material, created with natural​ wild flowers and a biopolymer. It has been carefully infused with aerogel for performance and durability. As well as being vegan and cruelty-free, super warm and light, it is the first time that this kind of flower has been used in a loose-fill insulation. Other vegetable-originated fibers exist but they are usually compressed in a nonwoven, roll to roll setting. The flower down technology has a patent covering the production method and unique combination of flower and biopolymer. It’s also the first time ever that an aerogel made of cellulose has been used in the process to increase thermal insulation properties. Each coat is filled with 400 to 550 grams of plant matter.
