The 11-model Sigma 2 family is designed for the golfer who prefers a putter on the softer side of the spectrum with the lively response of a firm face. Plus, a newly designed adjustable-length shaft comes standard on every putter in the line. Our studies show 8 out of 10 golfers are playing the wrong-length putter, and that consistency improves when you can customise the length for your stroke and posture.
