Vintage Penguin Munsingwear Ski Sweater

Not 100% sure what this little gem is made of but I would guess it’s wool. It definitely has wool in it, although it’s got a really nice stretchy vibe. Another Apres Ski piece for you! No rips or tears or visible stains. Excellent vintage condition. I’d date this piece to the 70’s or early 80’s. Size Small. Could be unisex but I think it’s a women’s sweater. Measures 17.5” pit to pit very stretchy due to the ribbing. Sleeves 21” from shoulder to hem. Length measured from CB to hem is 23”
