Kirala® bio fleece is a thermoplastic, aliphatic polyester derived from renewable resources, such as corn starch, tapioca roots or sugarcane. The polyactic acid fiber we use for the Sigyn series is 100% corn based, which makes it 100% biodegradable. Kirala® bio fleece is also naturally antibacterial. This means that we can also avoid using any anti-odor treatments.

Kirala® bio fleece dries quickly and is very light in comparison to its warming capabilities. A material that also works in humid environments, thanks to its hydrophobic properties. In conclusion, we think it is the perfect lightweight alternative for high paced activities in colder climates.
