         7 . The clothing article according to  claim 6 , wherein: for each of the plurality of heat-retaining parts, a sum of the heat-retention values W of each of the at least one type of material contained in the respective knitting thread with which that heat-retaining part is knitted falls in a range of not less than 25.0 to not more than 50.0. 
     
     
         8 . The clothing article according to  claim 6 , wherein:
 each part of the clothing article other than the plurality of heat-retaining parts is knitted with a respective knitting thread including at least one type of material; and   for each of the parts of the clothing article other than the plurality of heat-retaining parts, a sum of heat-retention values W of each of the at least one type of material contained in the respective knitting thread with which that part is knitted is less than 12.5.   
     
     
         9 . The clothing article according to  claim 1 , wherein:
 the clothing article is legwear that covers at least a knee, a heel, and digits of the lower limb or armwear that covers at least an elbow and digits of the upper limb;   the clothing article is knitted with a circular knitting machine in a continuous manner from (i) an opening through which the lower limb or the upper limb is inserted to (ii) the digital part for the lower limb or the digital part for the upper limb; and   each of the plurality of heat-retaining parts is knitted with a respective knitting thread containing fibers having a moisture-absorbing and heat-generating property.   
     
     
         10 . The clothing article according to  claim 9 , wherein:
 the fibers having the moisture-absorbing and heat-generating property are acrylate-based fibers;   the acrylate-based fibers constitute not less than 25% of each of the knitting threads used for the plurality of heat-retaining parts; and   each of the plurality of heat-retaining parts is knitted with the same knitting thread.   
     
     
         11 . The clothing article according to  claim 1 , wherein each of the plurality of heat-retaining parts is knitted with a knitting thread containing acrylate-based fibers that have an official moisture regain of not less than 35%.
