Don't let winter breathe down your neck while doing good by the entire world. This biodegradable snood features a biocatalyst technology that encourages microorganisms present in landfills to break down the fleece within a year compared to hundreds with ordinary fleece. This additive is free from harmful chemicals and also helps prevent microfibre pollution. And in case you were wondering, due to the innovative way this headband has been built, it will never fall to pieces before it reaches its final landfill destination.
