BioPuff® is an insulation designed to keep you warm whilst regenerating damaged wetlands. Increasing biodiversity, capturing carbon and ensuring a resilient industry for the future. This next-generation insulation, which reduces reliance on feather and synthetic fillers, is created by extracting fibres from plants that are grown on regenerated wetlands. BioPuff® is warm, puffy and has exceptional loft – it’s also cruelty-free and traceable all the way from plant to puffer.
