Water repellent parka
The coating is a resin, that is generally applied to the fabric to give consistency and toughness to the material.
A fabric is water repellent after special treatments to make it resist water: the drops of water do not remain on the fabric, but slip away. Water-repellent fabrics have a certain degree of porosity so they are permeable to air and water vapor. They allow the passage of water when the hydrostatic pressure is high (for example during heavy rain).
Most Peuterey items are made with PFC-free fabrics. PFCs are chemicals containing perfluorinated and polyfluorinated substances used in waterproofing resins. They are extremely polluting for the environment and dangerous for the health of humans and animals. Peuterey pays attention to the eco-sustainability of its products, therefore uses PFC-free fabrics.
