my Touring bag was bought a year before they did a PVC Lined version,
now I have found a Local sewing jobber to get a liner layer added..
will delay needing to pull out the rain cover a while longer ..
Touring bag puts the D rings in the back seam for the bag frame.. FWIW..
a strap around the load to pull it down and out of the way of the handlebars
Is probably useful ..
