The PING Sigma 2 Valor Stealth putter is packed with some exciting new features to help you putt better. Read on to find out more about these flat sticks.

Dual-Durometer Face

PING uses 2 layers to make up the dual-durometer face, made out of a material called PEBAX. The outer layer is soft, like a pencil eraser, for a softer feel on short, delicate putts. The inner layer is firmer, like tire tread. This firmer layer gives excellent distance control on longer putts.

Adjustable Shaft

PING first brought an adjustable shaft to the PING Nome model. That iteration had its limitations that the engineers addressed in the Sigma 2 line.

Each putter in the line can be adjusted between 32 inches and 36 inches using system that's built into the shaft. Simply take the tool and turn it left (adding length) or right (shortening length). Each full turn equals 1/4" on length.

TR Technology

The face of the PING Sigma 2 putters have the company's patented TR technology, which stands for "true roll" technology. The grooves are cut to different depths, deeper in the sweet spot and shallower on the heel and toe. This variation of depth gives you more consistent ball speeds, helping mishits go a similar distance as pure strikes.

The PING Sigma 2 Valor Stealth putter is a heel-shafted mallet that has a high MOI and easy alignment aid that help you make more putts. It has a head weight of 365 grams, for a stable smooth stroke. The Sigma 2 Valor also fits either a straight or slight arc putting stroke.
