Castore and Andy Murray, the Scottish tennis player and an investor in the brand, have launched a co-branded sustainable apparel line for tennis and lifestyle. Murray bought an undisclosed stake in Castore in March, in addition to signing an £8 million (€0.75m-$0.83m) agreement to be its global ambassador. The new apparel line features a newly created logo that combines the Castore wings with “AMC” for Andy Murray Castore. The different products are named after cities where Murray has won a tournament or places with a particular meaning to tennis. All pieces are made from regenerated nylon and recycled yarn. Murray will be wearing the collection on all court activities, starting with the 2019 Davis Cup.
