On the front of the sweatshirt there is a large print with blue text in French, which reads "THÉORIE DU CHAOS" and "LE PAPILLON". Below it is the English text: "A VERY SMALL CHANGE IN INITIAL CONDITIONS CREATES A SIGNIFICANTLY DIFFERENT OUTCOME". Below is ornately written "effet papillon", which refers to the so-called "butterfly effect". The sweatshirt has a classic cut with a large kangaroo pocket and long sleeves.
