Designed for children weighing less than 66 lbs (30 kg), the Petzl Ouistiti harness is especially easy to put on and adjust. It does not require a connector to be fastened, and the adjustment system is difficult for a child to access to prevent unwanted adjustments. The perforated foam structure and the front tie-in point favor comfort while climbing. The rear attachment point allows the child to be connected for other specific activities.
