Vintage Chicago Bears Kid Size Jersey by Franklin
Here is an awesome vintage jersey from the 1980s by Franklin. 100% polyester and made in the USA. Dark blue with Bears swag, and the number 4 on the back (Jim Harbaugh?) Light weight, soft and comfy. It's in amazing condition, and has years of life left. The tag says Medium, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)
Chest (armpit to armpit) 16"
Shoulder to end of sleeve (including cuff) 7"
