you might want to check out some of the canvas materials used by tent makers... it is available in various weights... all the way from 8 ounce to say 15 ounce. For the bottom of the bag you could double up the canvas.
the tent canvases are really nice materials because they are not waxy or sticky.... and they are designed to fight off mildew... yet they breathe very well...
google "sunforger canvas" for more information.
