Himespau,
Fwiw the Grundens one I got thru Riv Bike, is a thick PVC with a nylon backing.
so the fabric feel is on the inside.. It is a HD piece, not so light and compact.
I'm Commuting all the time with it and a Sou Wester in the Pannier ..
C.A.T., in Eugene sews a few sizes.. lighter fabric, interior coating.
Thinking : if you call and send a 3 layer fabric for them to work with,
those have a mesh lining surface..
I just had a pair of well used 3 layer Rain Pants de-laminate,
liner and coating separated from the shell . was my Fave pair..
