I Claim  
     
         1 . Back secured to a jacket or the like for fastening bottles of compressed gas for diving activities, in which said back consists of a main body made of a relatively soft and impermeable material and is provided inside with one or more chambers which can be filled up with a suitable non-compressible fluid supplied through inlet and outlet hubs obtained on said main body.  
     
     
         2 . Back according to  claim 1 , in which said chambers are intercommunicating.  
     
     
         3 . Back according to  claim 1 , in which said body consists of at least two overlapping strips joined on their edges by means of sealed thermoweldings.  
     
     
         4 . Back according to  claim 3 , in which said strips are joined on their edges by means of sealed seams.  
     
     
         5 . Back according to  claim 3 , in which said strips are sealingly joined in areas within said body of the back, so as to provide for partitions separating said intercommunicating chambers.  
     
     
         6 . Back according to  claim 5 , in which at least a passage for the non-compressible fluid filling up said chambers is obtained within said partitions.  
     
     
         7 . Back according to  claim 1 , in which said main body comprises an air outlet hub.
