Vintage Mens Long Sleeve Sweater by Jantzen
Here is a sweet long sleeve sweater by Jantzen. Feels like acrylic or a blend, and made in the USA. Light blue and wine red on a dark blue background, in a handsome geometric pattern throughout. Medium weight, but plenty warm. Super comfy and in excellent shape. The tag says Medium, but here are the measurements. (refer to the last pic above to see how I measure shirts)
Chest (armpit to armpit) 22"
Shoulder to end of sleeve (including cuff) 25"
