According to reports in Boardsports Source, Kelly Slater has made a formal offer to acquire a majority stake in Firewire. The recent move by the American surfer and 11-time world champion appears to be related to his interest in producing eco-friendly surfboards, as stabmag.com quoted him saying, it is time for the industry, and for himself, to work on “lessening materials impact.” Besides his sporting career, Slater was in the news last year. He left his long-term sponsor Quiksilver, in April, and then launched his own surf apparel label, Outerknown, backed by Kering, in September.
