Yes, but perhaps not for 20 to 30 liter sacks...
And I agree with Toby, a "free-flow" back is not really worth the effort for such a small bag... and neither is a raincover. Drybags and robust sack are enough.
My 0.02 $ would be BlueIce Warthog (old 26 liter one on sale, or the new 28 liter version).
