This is a rare, original Polo Ralph Lauren men's motorcycle jacket made of cow leather in rare distressed pre-stained black color (with very faint bluish "stains" mimicking motor oil and water damage.

It is in size XL/TG. It's not huge and probably runs just a little bit smaller than the size suggests (I am size L and it's just a little loose on me.)
The jacket has a motorcycle/biker look.

Outer sleeve - 25 1/4"
Inner Sleeve - 18"
Back Length - 25"
Front Length - 27"
Pit to pit - 22 1/2" - 23"
