The Java Jr Combo is a fantastic entry-level kit designed for kids four years and above. The Java Jr features shatter-resistant polycarbonate lenses and a split strap for a fit that won't slip, holding the soft face skirt snug against the face for a no-leak, comfortable seal. The classic j-shaped Tonga snorkel is fitted with a mouthpiece sized for kids with a flex section that virtually eliminates mouth and jaw fatigue.
