I have worn the same Coldwave leather bibs for the last ten years with no issues. No salting, whatever that is, no treatment and no seam splitting. I did nothing more than wipe them down from time to time with a wet rag. I decided to go with Klim this year because the leather is heavier than I prefer but more than anything it appears to be shrinking arround my mid section... or something to that effect. There is no doubt that they are extremely warm as well. I hope I can say the same for the new bibs.
