Here is a wonderful long sleeve sweater by Jantzen. Feels like it could be a wool blend, and made in the USA. Red sweater features a vee neck with black initials embroidered on the left breast. Fairly light weight, but warm, soft and comfy, and in amazing condition with tons of life left! The tag says Large, but here are the measurements taken laying flat (please refer to the last pic to see how I measure sweaters)

Chest (armpit to armpit) 23"

Sleeve 22"

Length 21"
