Product Description: "Shadan" is a material that reflects infrared rays, suppressing the rise in temperature inside clothing and rooms, and has both energy-saving effects that improve air conditioning efficiency and UV cut effects. The tag has been removed. It was stored as shown in the last photo, so there are creases. I think it will not be a problem to wear.
