Holes, tears, snags or cuts in the webbing (Red Alert yarns could possibly be showing)
Stitching is broken or worn

Quite simply, great and bad the sling continues to be compromised dramatically. Slings with damaged may never be repaired, but discarded properly. If the metal fittings with the sling still seem useful though the webbing is broken, it is possible to cut the fittings loose from your webbing and still have them mailed in into a manufacturer to become re-sewn with new webbing (however, the fittings have to be proof-tested for strength at that juncture).
