Here is a super cool vintage long sleeve sweater by Down Under (by Chandler Bryan). Feels like acrylic or an acrylic blend. Great looking vibrant red fabric with an adorable blue kangaroo on the left breast, and a vee neckline. This one is medium weight, and incredibly 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) 22"

Shoulder to end of sleeve (including cuff) 29"

Length 27"
