Washer Fluid Bottle Bracket...

I am refurbishing my washer fluid bottle bracket.

The bracket itself looks like it was/is black, and faced with an open- 
cell foam, but what is the strap that secures the bottle made of?   
I've got two short ends riveted to the bracket, and they appear to be  
some sort of white rubberized canvas.  Is it just canvas, or  
elastic?  I'm really not a stickler for detail (it is my daily summer  
driver), but I would like it to be close to correct, in the interests  
of functionality.

Thanks--
