Titleist Speed is the project that has been bringing more speed to golfers games around the world. These hybrids are part of that project & are made to make the ball fly off the face as fast as possible to give you the most distance possible. The crown & the face have been made thinner than ever before. The super thin crown gets the weight moved deeper in the club face to enable a higher launch for a longer flight, adding distance to your shots. The face is 16% thinner & this increases the speed of the ball while also adding forgiveness to once again get you hitting the ball further, even with off centre hits.
