British retailer END. brings Carhartt WIP on board to help celebrate its 15th anniversary. The result is a collection that pays tribute to both the workwear heritage of the American label and the forward-thinking nature of the WIP line. It’s filled with streetwear staples, each covered in shades seen throughout Carhartt’s history — just like this concrete grey sweater. A co-branded patch on both sides completes the look, reflecting the modern and progressive attitude to design that have defined WIP since its earliest days.
