Oakbrook Sportswear Sears Leather Motorcycle Jacket Vintage 1960s

I know nothing about this item, found it in my dads closet as I was cleaning. See photos for condition etc. I am about 6’ and 175 lbs. As you can see, it fits me, but would probably be better for someone slightly smaller.
Overall it appears to be in decent used condition for a vintage item, with scuffing and wear. Could probably benefit from a cleaning.
Please contact me if you want more info, measurements, etc.
Thanks
