petzl macchu children's harness (blue) petzl intended for children weighing less than 40 kg (88 lbs.), macchu is a seat harness designed for climbing. its fully adjustable design, and optional body shoulder straps, enable this harness to adapt to both your growing child's needs and climbing levels from top-roping through lead climbing. identical to adult harnesses, the waistbelt and leg loops are padded to ensure comfort while suspended. the two doubleback buckles maintain a uniform fit and position of both the tie-in points and gear loops as your child grows. the differentiated color of the belay loop allows a quick visual check to ensure the belay device is properly attached. the harness has two gear loops and an accessory loop for a chalk bag, to be just like the grown-ups.
