Here is a super cool short sleeve sweatshirt from Alex Sport. 100% acrylic and made in Belgium. Vibrant red with white stripe accents. Six inch zipper front. Three section pocket on the back. I assume this was designed as a cycling shirt, but be creative! Medium weight, warm, soft, and comfy. It's in amazing shape with tons of life left! The tag says 7, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 23"
Shoulder to end of sleeve (including cuff) 10"
Length 31"

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