       9 . The structure of  claim 1 , wherein the water-retentive member comprises an antifungal agent. 
   
   
       10 . The structure of  claim 6 , wherein the water-absorptive polymer comprises an antifungal agent. 
   
   
       11 . A structure for cooling, comprising:
 a cover having a first side and a second side, and   a water-retentive member, wherein the water-retentive member comprises
 a bag having a first side and a second side, and 
 a water-absorptive polymer that is adhered to an inner surface of at least one of the first side and the second side of the bag, or that is disposed in at least one of the first side and the second side of the bag, 
   wherein the water-retentive member is disposed inside the cover;   wherein the first side of the cover has a moisture-permeability of 500 to 3,000 g/m 2 ·24 hours as determined by the Lyssy Method;   wherein the first side of the bag is moisture-permeable or water-permeable; and   wherein at least one of the second side of the cover and the second side of the bag is water-impermeable.   
   
   
       12 . The structure of  claim 11 , wherein the first side of the cover comprises a fibrous layer and an air-permeable sheet layer. 
   
   
       13 . The structure of  claim 12 , wherein the air-permeable sheet layer is an air-impermeable polymer film having openings. 
   
   
       14 . The structure of  claim 11 , wherein the first side of the bag is made of a fibrous material. 
   
   
       15 . The structure of  claim 14 , wherein the fibrous material is a nonwoven fabric. 
   
   
       16 . The structure of  claim 11 , further comprises water-absorptive material disposed in the bag.
