The top of the Blackberry cap has sides with felt interlaced in black and dark blue tones. It thereby pays homage to the brambles that penetrate Serralves Park, and in the summer produce juicy blackberries for everyone's delight. They are models that contain the spirit of Nature and Serralves Park, due to the magnitude and beauty of its green spaces, of great relevance to Serralves and the city of Porto. The Olives Capsule Collection for Serralves is the result of a partnership between Serralves and Olives, in the promotion of hats inspired by Nature and Serralves Park's natural beauty, in harmony with the brand's spirit of innovation. This is the first time for the hat industry, that hats have been made with felt interlaced in the brim and top.
