Nike Patterned back l/s top

Graphic black/white ON BACK ONLY, plain black front and sleeves. Unique Nike workout top. Lightly worn. Never been in dryer and smoke free home. Note that it is a medium but I think fits more like a small. The fabric has super tiny “holes” that are meant to breathe (I honestly never noticed until now!). Best shown in the pic of the tag and u can see tiny holes on the interior white fabric. Hardly visible otherwise.
