Pendleton wool on mackinaw
Hey folks, curious if my forest green single mackinaw (images attached) was made using Pendleton wool? As the tag just states Made in USA (VS Made in USA with imported materials)... Unless there was a period they were using other USA mills after Pendleton?
Any info would be greatly appreciated, asking as it feels quite different to my black and red plaid mackinaw from the woolmark era which used Pendleton and feels more burly.
