Russian apparel brand Bosco Sport has become a leading sponsor of the 2014 Winter Olympics in Sochi. A deal signed Wednesday also makes Bosco Sport the exclusive outfitter of Russian Olympic teams for the upcoming Winter Games in Vancouver through the Summer Games in Rio de Janeiro in 2016. Sochi organizing committee chairman Dmitry Chernyshenko signed the tier one sponsorship deal worth more than $100 million with Mikhail Kusnirovich, the head of Bosco Sport's parent company. Bosco Sport also signed a deal to produce licensed apparel with the Olympic symbols through 2016. Russian organizers said earlier this month that they expect to attract more than $1 billion in revenues from domestic sponsors of the Sochi Games.
