This vest was made in Mexico more than likely late 60's - early 70's. It's extremely rare and I've never seen one like it before. 75% wool, 25% acrylic and extremely cozy. I'm personally a 42 and it fits me well, but a little roomy. I would say it's closer to a 44. Looks good on women as well. Amazing palette, two front pockets and great yoke and details.
