Who's ready for some baseball? Chicago Cub fans are! I have a men's size XL (unisex) lightweight short-sleeve shirt just in time for the season. This shirt is 100% polyester, and measures 24" across the chest, and the length of this shirt is 27". This shirt could be men's or women's; it was mine, and it is very lightweight and comfy. The only reason I am selling it is that it is too big on me now, so it is time to pass it on.
