The vegetable wool
Kapok is a precious and totally organic fibre obtained from the fruit of the Ceiba Pentandra, a sacred plant that grows up to 60 metres high, widespread in the rainforests of South America. Known as 'vegetable wool' for its extraordinary lightness, kapok is a hollow fibre composed of 80% air, with a very low density (0.35 g/cm3). Because of this, kapok is the lightest natural fibre in the world.
Totally organic
Kapok fibre grows wild in pristine forests, no intensive cultivation is required and the fiber is harvested by hand. No fertilizers or pesticides are used in its cultivation.
Naturally insulating
The structure allows the kapok fibre to trap a large amount of body-warmed air thus creating an insulating barrier that protects against temperature changes.
Soft and hypoallergenic
High-quality and soft, it dries quickly, is hygroscopic and has natural antibacterial and hypoallergenic properties.
