We create apparel that stands up to the highest and harshest conditions on Planet Earth.

Our performance base design process uses feedback from professional mountaineers & mountain athletes to create apparel to help you perform at your highest level. We partner with high quality textile mills and factories from around the world to ensure that our base materials and construction are top of the line. Then we rigorously test both the design and the materials every step of the way until we have created something that we are proud of.


Durable, long lasting performance is the foundation of all Pertex® fabrics and is never a point of compromise.
