Federer currently plays with a customised Wilson Pro Staff 6.1 90 BLX tennis racquet, which is characterised by its smaller hitting area of 90 square inches, heavy strung weight of 364 grams, and thin beam of 17.5 millimeters. His grip size is 4 3/8 inches (sometimes referred to as L3). Federer strings his racquets at 21.5 kg mains/20 kg crosses pre stretched 20%, utilizing Wilson Natural Gut 16 gauge for his main strings and Luxilon Big Banger ALU Power Rough 16L gauge (polyester) for his cross strings. When asked about string tensions, Federer stated "this depends on how warm the days are and with what kind of balls I play and against who I play. So you can see – it depends on several factors and not just the surface; the feeling I have is most important."
Federer is one of the highest-earning athletes in the world. Forbes listed him as number 4 in their list of the top 50 highest-paid athletes in 2011. He has a contract with Nike footwear and apparel. For the 2006 championships at Wimbledon, Nike designed a jacket emblazoned with a crest of three tennis racquets, symbolising the three Wimbledon Championships he had previously won, and which was updated the next year with four racquets after he won the Championship in 2006. In Wimbledon 2008 and again in 2009, Nike continued this trend by making him a personalised cardigan. He also has his own logo, an R and F joined together. Federer endorses Gillette, Jura, a Swiss-based coffee machine company, as well as Mercedes-Benz and NetJets. Federer also endorses Rolex watches, although he was previously an ambassador for Maurice Lacroix. Also in 2009 Federer became brand ambassador for Swiss chocolate makers Lindt. In 2010 his endorsement by Mercedes-Benz China was extended into a global Mercedes-Benz partnership deal.
