Tested on the world's toughest trails by our pro mountain bike athletes, our Youth Defend Pants deliver durability you can trust with additional storage for all-day park laps. The tapered lower leg with stretch mesh inset provides a race-ready fit, which reduces snags and adds cooling. 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. 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.
