Anatomic Pro Cut Bib Shorts made with Newport fabric (22% lycra 78% polyamide). Antibacterial "Coolmax Techno" padding. At the base of the chamois is a layer of crossed microfiber fabric with an antibacterial treatment. A layer of Coolmax fabric then covers the padding where it comes in contact with the skin. The micropores that cover the entire surface of the chamois guarantee maximum breathability. You can wash the Coolmax Techno padding and no cream is needed to soften it again before use. Even after many washes, its performance is not reduced.
