Vintage men’s quilted long underwear/long johns/puffy pants, see measurements

Color in person matches the first 2 pictures. Last 2 pictures show the inside. No flaws noted. Tagged as a medium, but as these appear to be a 60s-70s piece, see measurements to ensure desired fit. Do your own research prior to purchase, as these have no material/manufacturer tag. Classic vintage long johns, long underwear, puffy pants…call them what you will, these were designed as a base layer to wear as an extra layer of warmth and will do their job well. The material feels like mostly polyester. Knit cuffs at the bottom. The snaps are in excellent condition - no rusting, no scrapes in the paint.
