"Triplepoint® Ceramic is a highly technical process in which multiple high-pressure coatings with microscopic ceramic pores are applied to fabrics in such a way that they lock into the fibers and cannot separate or delaminate. The exclusive Triplepoint® Ceramic fabrics, which are waterproof breathable, are especially designed for alpine expedition wear."
