This unique to Fox design adds a bit of style and improves ease of movement. The pants are built with our exclusive TRUDRI moisture management technology. This performance fabric rapidly wicks moisture from the skin to keep you dry and comfortable. The Sirus pants will match you stride for stride on your morning run, keep you comfortable and focused at the gym, and offers a relaxed garment for a day spend on the couch.
