Updated with Babolat's new HTR System, the Pure Drive's graphite layup has been reengineered for higher torsional rigidity, resulting in more efficient energy transfer to the ball. To help with vibration dampening, Babolat has devoted more space in the shaft to SWX Pure Feel, a thin and extremely flexible viscoelastic rubber that sits between the racquet's carbon layers. Additional features include FSI Power Technology, which optimizes the grommet system and string spacing for higher levels of power and spin.
