I had used Terry saddles in the past and since they changed to the new fabric on the Zero X, I sent it back. That weave material does trap salt and odor. It was almost sticky when I rode. I sent it back before things got too bad. My only suggestion other than a different saddle is to try some type of scotch guard or seam sealer like you use on camping tents to waterproof. I am not sure it would be 100%, but may help. For what it's worth, I think The Selle Italia Lady Gel Flow is pretty much the same as the butterfly. Selle Italia makes Terry saddles.
