What we say...
The Yes! Golf Donna II Putter is composed of two different materials. The face is made of aviation grade 6061 aluminium and the body is made of 303 stainless steel.
The combination of a light face and heavy back generates very high MOI. The design of the putter is a combination of a mallet and cavity-back blade.
The Donna II is the Pro-requested toe-down version of the popular Donna. The MOI is maximised by the heel and toe weighting through the face.
