Made from 100% natural viscose fibres. There are no plastics, toxins or chemicals in these towels. Viscose is the generic name for cellulose fibres/wood pulp and as such, they can also include other plant fibres -such as bamboo. Due to these natural fibres, these towels are all 100% biodegradable. The fabric is made by hydro-entangling the fibres so that no binders, chemicals or additives are required. These towels are lighter in weight than our regular towels (40 GSM instead of 50 GSM) and are a great eco-friendly alternative.
