The Fox Demo FR short is made from a durable 2 way stretch outer shell for maximum flexibility when in the ride position. Airflow is a must and this is why Fox perforated the shorts throughout with a laser to ensure high quality and optimal airflow. An active bottom ensures proper coverage while pedaling. The Demo Dh utilizes an adjustable front ratchet closure and side adjusters to dial in your perfect fit. To top it all off, zippered hand and leg pockets ensure your items stay secure and safe.
