Made from a lightweight 4-way stretch fabric you've got unrivalled flexibility for hard pedalling uphill efforts and the freedom to move as you rush headlong into the downhills. Weight is also minimised via the bonded hems, which also have the added benefit of reducing chafing. Riding XC trails hard in summer will soon see you sweating. But thanks to engineered airflow zones, with laser-cut perforations, there's plenty of cooling airflow to be had. TruDri technology also ensures moisture is quickly drawn off the skin, leaving you dry and fresh during and after your ride. At the waist Fox's proven ratchet system gives you brilliantly quick and easy adjustment, locking your Flexairs in place. And if you encounter damp trails, the DWR (Durable Water Repellent) will fend off mud and water splashes.
