Leather
Jackets and bags with decades left in them.
The find
Leather with patina is better than leather without it. A cracked jacket still has decades, if you condition it.
What to look for
patina color that's changed with wear cracks surface, not through the hide lining torn lining is an easy fix hardware solid zips, or easy to swap
How to score
Surface cracking is repairable — through-holes are the only real dealbreaker. Condition twice a year and it outlives you.
