Important information about care and maintenance: 1.It is important to wash this garment frequently, especially after an aerobic situation with sweat, or if it´s been exposed to any chemical product which might affect its properties  2. Machine wash in cold water without other garments which might scratch it (like jeans). 3. Do not use softener. 4.
