This Deuter product is free of per- and polyfluorinated chemicals, thus reducing the use of harmful substances that pollute the health.
PFCs are used, among others, as a coating to protect against the rain as they have waterproof, anti-smudge and anti-grease properties.
Instead, Deuter now uses a DWR (Robust Water Repellency) treatment, which is harmless to both health.
