The perfect do-it-all short, April to October. The River Rock features a ten-inch inseam to cover little legs for protection during rock sliding contests or long days on the dirt bike. Quick Dry fabric promises what it delivers, fast-to-dry function after a swim or wade in the creek, with enough durability to last the season. The elastic waistband, with drawcord, allows the River Rock to grow with your boy, making them last just a little longer.
