Weeell, maybe not. One of the first things we were advised about the locals
up in Alaska was to avoid purchase of mukluks/parkas from them which
employed an animal acid - urine- to preserve them.

Those kinds of things keep you warm outside at -30, but can drive you into
the cold again if you let them thaw indoors.

Not oil. Vegetable tannins. Actually the only way leather is 'tanned'
which is
the process of changing it from raw skin to leather.
