Jack Wolfskin has teamed up with the National Trust in the U.K. for the launch of an exclusive eco-friendly range of outdoor clothing for men and women. The collection comprises t-shirts, fleece tops, jackets and trousers. The pieces in the range are PFC-free and are made using alternative treatments for durable water repellency. The fleece top is also made from recycled PET plastic bottles. In addition, the collection features Jack Wolfskin's Texapore Ecosphere waterproof-breathable membrane, manufactured from remnants from the production process. Every purchase from the Jack Wolfskin x National Trust collection will support the work of the National Trust to look after the great outdoors. The National Trust is an independent charity and membership organization for environmental and heritage conservation in England, Wales and Northern Ireland, and the largest membership organization in the U.K.
