Tetron is a type of polyester or blended fabrics with cotton.
Advantages of Polyester
Resists wrinkles and shrinking
Tetron is a fabric made from two different materials: polyester (65%) and rayon (35%). Hakama made from tetron aren’t going to shrink like ones made from cotton. Cotton “wicks” perspiration away from your body. So, cotton will keep you cooler and drier. However, because polyester absorbs less moisture, it dries faster and is less likely to get moldy. Also, mold only grows on organic material. So, obviously polyester is safe there, too. Polyester is more durable than cotton. So, a tetron hakama may hold up longer. It’s also more dirt-resistant. So, you won’t have to wash your hakama as often.
