FEATURES DF 2.1 can do amazing things other putters can't because of Lie Angle Balance, or L.A.B. for short. Lie Angle Balance gives every golfer the ability to consistently repeat the putting stroke with far less effort than with other putters. And it does this by eliminating torque. All DF 2.1 putters are manufactured and assembled in the USA. They're 100% CNC milled from 6061 aircraft aluminum. Includes matching DF 2.1 headcover
