A lot of our outerwear is made water-repellant with BIONIC-FINISH® ECO, a non-fluorinated and highly durable water-repellent textile finish. Most conventional water-repellent coatings on the market contain fluorocarbons, a harmful chemical group that decomposes very slowly in nature. BIONIC-FINISH® ECO is a safe and environmentally preferable option, free from fluorocarbons and other hazardous chemicals including PFCs (perfluorinated compounds), formaldehyde, and paraffin.
