NIKE leggings lot

Burnt neon orange, gray with gold metallic and olive green leggings all Size XS. Didn’t notice any flaws or peeling on the gray pants. Orange and olive pair have some kind of markings. I’m not sure what they are because I have an activewear setting on my washer only use active sport soap when washing and wash activewear separate + air dry It seems to only happen to my Nike leggings when I wash them hasn’t done anything to my gymshark, BuffBunny, Adidas. Still In great condition!!! 🔥FIRM🔥
