The Aerogel 9Hundred is a powerful game improvement racquet. It is maneuverable yet offers enough mass, thanks to its head-heavy balance, for solid hitting. Dunlop's Vibracore Technology provides a very comfortable and solid feel at impact. Offers good pop on serves, volleys and overheads. The open, fan string pattern produces plenty of spin and the sweetspot feels very generous. A solid choice for the 3.0 and higher level singles and doubles players looking to develop an all court game.
