Wind, rain or snow – our shell products are built to handle it all. Penguin uses Dermizax® by Toray Japan, a leading manufacturer of high-performance technical fabrics. Thanks to Dermizax® technology, the pants remain waterproof and highly breathable, even in demanding conditions. Our 3-layer Dermizax® line was developed for deep powder days. The fabric offers an optimal balance of durability, breathability and waterproof protection.
