I like the material better because it doesn't need to be oiled and kept like leather.

Unfortunately, one of the "biothane" leashes that I bought is coming unstitched at the handle after a few years' use.  I think this is a defect in the stitching, and has nothing to do with the "biothane" material itself.

Biothane is easier to keep clean and doesn't require the oiling that leather does.  It's also consistent handling in all weather, cold, and wet....  In the equine industry biothane is used for everything from saddles, bridles, harnesses, pack equipment, you name it.   I like biothane for some things, for other things I am "purist" and must have the leather.
