MACCHU® - Harnesses | Petzl Luxembourg


Comfortable sit harness for children

Designed for children, MACCHU is a comfortable sit harness. The waistbelt and leg loops are padded, offering additional comfort when hanging. The harness has a wide range of adjustability, allowing it to grow with your child, adapting to their size. The waistbelt buckles allow you to properly position the tie-in points, and the attachment loop is a different color for rapid visual inspection of the belay system connection point. It also has two gear loops and an accessory loop for a chalk bag, to be just like the grown-ups. For small children, it’s possible to add BODY shoulder straps, converting it into a full-body harness.
