This is a kids' size (160) T-shirt from the surf brand RUSS-K. It's made of a cotton and polyester blend, with a soft and pleasant-to-the-touch fabric. Because it's a blend with polyester, it's wrinkle-resistant and dries quickly after washing, making it very useful in the summer. I didn't realize 160 was a kids' size. I think it would also be a good fit for adults wearing a size S, or for women. To keep the price as low as possible, I haven't washed or ironed it, but it has been ozone disinfected. I would appreciate it if those who understand used clothing would purchase it. Thank you for looking.
