Here is an awesome vintage T-shirt by Collegiate Pacific. 100% combed cotton, and made in the USA. This was locked away in a trailer in 1988, and untouched until 2016. It is new/old stock, and has never been worn! And I'm not an expert on the Collegiate Pacific tags, so this could be late 70's or 80's, but I'm calling it 80's. Dark blue shirt with sweet Iowa State Intramural graphic on the front in red and white. This one is in mint condition, and incredibly soft and comfy. It is ready to finally live it's life after being locked up for 30 years! The tag says Medium 38-40, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 18"
Shoulder to end of sleeve (including cuff) 7"
Length 30"

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