Turn Junior loose on a choice piece of singletrack in the Pearl Izumi Mountain Bike Kid's Shorts. The SELECT Transfer fabric wicks moisture away form Junior's skin, so he'll be comfortable as he gives Mom and Dad a thorough multi-mile mountain bike beatdown. The lightly padded chamois will take care of his backside without feeling like he's back in diapers, and the side pocket has plenty of room for a snack, a little music, or valuable artifacts that he finds on the trail.
