Vintage Levi's Sta-Prest pants vintage 60s blue 34 30

Vintage Levi's Sta-Prest pants, vintage from the 60s, blue. Size 34" x 30". Tag has been removed from back pocket, these would have had the black Tab with gold lettering and Big E for products treated in the new Sta-Prest process — which guarded against wrinkles. They aren't really denim, they look and feel like soft broken in linen. Some overall signs of wear, these are vintage and broken in. So awesome. 1960s Levi's jeans.
