Vintage Men’s Stadium Sportswear sweater, crimson, shaker knit, wool, size M?

Gorgeous wool, shaker knit sweater with long ribbing section at hem! This looks like a college sweater that would display your varsity letter! Vintage vibes abound with the rich color and soft texture. There is a repair on the back and a pull or 2 (see last 2 photos). No tags with size or fiber content, but I’m guessing 100% wool and men’s size M (see measurements below) Overall in very good pre loved condition! 22 inches pit to pit 24 inches length
