<p>PURPOSE:To develop a golf ball exhibiting ideal high characteristics in a liquid center and string wound golf ball. CONSTITUTION:In a string wound golf ball consisting of a liquid center wherein a liquid is contained in a rubber bag, a string rubber layer formed outside thereof, and an outer skin for covering the whole, moment of inertia of this golf ball is 75-80g.cm<2> at 2 deg.C measurement and a measurement value of the moment of inertia at -3 deg.C has an increasing rate of 2% or less with respect to that at the 23 deg.C measurement.</p> |
