PETZL Macchu Children's Sit Harness – Violet | Adjustable Kids Climbing Harness

The Petzl Macchu is the ideal sit harness for children who are ready to advance in their climbing journey. Built for kids under 40 kg (88 lb), it bridges the gap between pediatric options and adult gear with a design that grows with your child.

Grow-with-your-child design

The waist belt and leg loops are fully adjustable, offering a wide range to support several seasons of use as your child grows. This flexibility helps families extend the life of the harness and reduces the need for frequent replacements.

Balanced comfort with ENDOFRAME technology

Using split webbing and foam, ENDOFRAME construction distributes weight evenly to minimize pressure points, so kids can climb longer with less fatigue.

Safety-first details

A dedicated colored connection loop provides a quick visual check for the belayer to confirm the attachment is correct before starting a route. Two gear loops and a rear accessory loop help kids learn gear management alongside adults.

Versatility and compatibility

For younger climbers with less defined hips, the Macchu can pair with Petzl BODY shoulder straps to form a full-body harness. This option is available separately for a tailored fit.
