Whistle & Flute clothes are made using organic fabrics and safe inks. Our kids all struggle with sensitive skin and we rest easy knowing their clothes are not going to irritate them. This is why all of our T-shirts also have screen printed tags to reduce sensitivity. All joggers and sweatshirts have easy to remove silk tags.
