Keen Footwear has converted a production line at one of its factories in Thailand to manufacture reusable and washable face masks. As part of its “Together we can help” campaign, the American outdoor footwear brand has donated 100,000 masks worldwide to people working in the retail industry. In Germany alone, about 17,000 masks were given to the company’s partners. In the next couple of weeks, Keen will start selling the masks, which are made from materials initially destined for the production of shoes.
