The applicability of the air bag system for measuring clothing pressure was studied by investigating the relationship between measured and calculated pressure. These values were obtained under the distinguished conditions which were the volume of the air bag, the curvature and the compression of the model, the cloths on the model and the deformation of elongation. And, the regression analysis was carried out by using differences between measured and calculated pressure which obtained under these conditions.
　As the results, the measured pressure from this air bag system changed according to these condition. But, the processed pressure from the formulas of the regression analysis very adapted to the calculated one. And, the clothing pressure and the comfort of the support type sportwears (swimming suit, reotaled, spat) were measured. The comfortable pressure level of these wears was 5 ～ 10 gf/cm² on the inside of them, for example, the part of the abdomen, the hip or the thigh. High 20 gf cm² pressure on the outside of them did not decline the general comfort sensation, for example, the shoulder strap or the waist band.
