The filling of the light duvet insert Harmony is made of vegetable fibers 60% Kapok fluff (another name is ceiba) and 40% Mulberry silk. Kapok fluff fibers are 8 times lighter than cotton fibers. Being the thinnest fiber among vegetable fibers, Kapok is elastic, which allows it to restore its shape well. In addition, Kapok has high wear resistance, and its temperature-regulating properties are similar to natural silk. The collection and processing of this fiber are done manually, and the processing does not require the use of chemicals, which makes the product completely eco-friendly and safe. The duvet insert 'Harmony' is made of 100% cotton of the original jacquard weave with a density of 300TC.
