Polygiene® Permanent Odour Control This dhb garment is treated with Polygiene® permanent odour control, helping to keep you fresh and odour free. Polygiene naturally inhibits the growth of odour-causing bacteria and fungi on fabrics, allowing you to wear more and wash less. Clothes can be worn several times before laundering. Polygiene will help to make your clothing last longer as bacteria and excessive washing do not break down fibres as quickly as they do on untreated material. Using components of natural silver salt made from recycled silver, Polygiene meets the highest standards for skin safety and hygiene, and is guaranteed to last for the lifetime of the product. .
