The Fox Flexair Lined Shorts are built around 4-way stretch fabric with strategically laser-cut airflow perforations that flex and breathe through every phase of the pedal stroke. Ultra-light moisture-wicking construction keeps you cool under effort, while a DWR finish actively sheds moisture, dirt, and debris on the trail. Included is a removable liner short with a dual-density chamois, giving you the support of a padded kit with the flexibility to ride with or without it.
