Durable Mountain Bike Pants with Additional Storage for All-Day Park Laps Fox Defend Pants have been tested on the world's toughest trails by their pro mountain bike athletes. The tapered lower leg with stretch mesh inset provides a race-ready fit, which reduces snags and drag. The TruMotion all-way stretch main material ensures a high level of pedal efficiency, helping you ascend the toughest climbs so you can enjoy the descent. Cordura knee panels bump up the durability to provide enhanced abrasion resistance as you rip. Stay cool all day thanks to a combination of TruDri fabric to move sweat away from your body, plus laser-cut perforations in the front and rear of the pants to increase cooling. The material is finished with DWR, which sheds moisture, dirt, and debris while you shred, and the proven race-ratchet closure makes on-the-fly adjustments a cinch.
