PFC-Free
Per- and polyfluorinated chemicals (PFCs) are a family of human-made, fluorine-containing chemicals. They have long been used to add water and stain repellent properties to technical fabrics. PFCs can harm the wearer of the garment and damage nature. Incredibly resistant to breakdown, these pollutants have been found across the globe; they can remain in the environment for many years after release. In response, a growing number of PFC-Free products are being developed, designed to provide reliable water repellency without the use of these harmful chemicals.
Recycled
Patagonia first made a fleece from recycled plastic bottles in 1993, since then more and more brands have been ‘recycling rubbish’ to make the high-performance clothing and equipment that we all love to rely on in the outdoors. There are now many different types of materials and products made from waste that would have otherwise ended up in a landfill.
