i wore a regular police style leather jacket back in the day, still have it but it seems to have shrunk. i have the same style jacket now made by wilson with thinsulate, pretty warm and big improvement over the older jackets.
leather is good if you're sliding down the road on your back..get with the times and go with textile..lighter and doesn't wear you down from the weight.
Leather doesn't melt into your dermal layers like plastic when taking a "slideride."
Again, your mileage may vary...
My pop willed me his WW2 bomber jacket...about 1963. Later Sears leather...but I seldom wore leathers in those days, favoring Levi jacket and trousers. I was tougher then... Naturally I never wore a beanie...too dangerous!
Levi jacket most of the time and a leather jacket from tijuana Mexico, loved that jacket. You might be able to shop on line I'm pretty sure they still make them
