This is Adidas innerwear. My child wore it when they were in elementary school playing soccer. The size markings are fading due to washing. Also, I wrote their name on it, so I've blacked it out, and the inner tag has been cut off. It has been used, but there are no tears or stretching, so it should be fine to wear. Please be aware that this is a used item before purchasing. ● Size: 160 cm ● Material: Likely nylon and polyester (cannot confirm as the tag has been cut off)
