Signature by Levi Strauss & Co.™ Boys' Uniform Pants are a warm-weather pair that's easy to wear. They sit at the waist and have a slim fit through the seat and leg. Soft, stretchy twill flexes and moves with him. Elasticized waist makes for quick changes, and fully functional hidden drawcord (sizes M–XXL only) makes getting a customized fit a cinch.
