Here is a cool vintage jacket by Ebert Sportswear. 100% nylon. Bold red jacket with Warwick Marching band (Lititz, PA) graphic on front and back in white. Zippered front. Fairly heavy weight with fuzzy lining inside, so it's super warm and comfy. In amazing condition with tons of life left. The tag says Medium, 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) 26"
Length 30"

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