In this paper, four primary hands and total hand, suggested by HESC, of Korean summer suits for men had been judged by the experts in factories, so called by means of hand judgement. And the mechanical properties of those suits had been measured by KES measuring system, developed by kawabata. And then the regression eguation which hand value can be calculated from mechanical properties can be obtained from sensory properties and mechanical properties of these suits by means of a step wise block regression analysis. And hand and mechanical properties between Korean summer suits and Japanese had been inspected, and compared each other. The result obtained were as follow. 1) Correlation coefficient between experimental and the regressed hand values of Korean summer suits were higher than that of Japanese. The saturation of R with increasing terms of Xi suggests that the behind terms of after the saturation can be ignored.2) The order of contribution of each of the characteristic values to the hand value were as follow. a)Stiffness; shearing properties>bending properties>surface properties>tensile properties>compression properties>WT b) Crispness; surface properties>shearing properties>compression properties>tensile properties>bending properties>WT c)Fullness and softness; compression properties>tensile properties>WT>shearing properties>bending properties>surface properties d)Anti-drape stiffness; bending properties>surface properties>shearing properties>compressin properties>tensile properties>WT
