Here is a super cool vintage long sleeve sweater by Mc Briar. Feels like acrylic or an acrylic blend, and made in the USA. Vibrant green fabric and a vee neckline. This one is light weight, but warm, soft, and comfy. Nothing fancy, just timelessly classic and handsome. It's got pilling throughout, but other than that it's in excellent shape with tons of life left! The tag says Large, but here are the measurements. (refer to the last pic above to see how I measure shirts.)

Chest (armpit to armpit) 24"

Shoulder to end of sleeve (including cuff) 26"

Length 28"

This item is sold from a vintage boutique in Roanoke, VA.
