That's cos it's only the coating on the back that adds waterproofing to cordura...once that rubs off it's porous.
Floating liners are the way!
sort of, the coating on the back side helps prevent water sluicing through the fabric in volumous amounts but does little to prevent wicking, corduro begins to let water through as soon as the water no longer beads on the face side. Why i dont bother with undercoated fabric for my camping tent, a rain fly with a dwr coating on the face works better. cordoro is much heavier than the nylon for tents but it works in the same way
