The Petzl Macchu Harness is a comfortable and fully adjustable children’s climbing harness designed to grow with young climbers. Its wide range of adjustment makes it suitable for children of different sizes and allows the fit to be adapted as they grow or when wearing different layers of clothing.

Designed with many of the practical features found on adult climbing harnesses, the MACCHU is suitable for climbing sessions where comfort, easy adjustment and efficient gear organization are important. Its padded construction provides comfortable support when hanging, while the adjustable waistbelt and leg loops help create a secure, personalized fit.

Adjustable Fit for Growing Climbers

The Petzl Macchu Harness features a single-size design with a waistbelt adjustable from 54 to 65 cm and leg loops from 34 to 46 cm. DOUBLEBACK buckles on both the waistbelt and leg loops make it easy to adjust the harness to the child’s size and accommodate seasonal clothing.

The two waistbelt buckles also allow the tie-in points to be properly centered. This helps maintain a balanced fit while keeping the belay loop correctly positioned.

Comfortable While Hanging

The MACCHU uses FRAME Technology to distribute pressure effectively across the waistbelt and leg loops. Padded waistbelt and leg loops provide additional comfort when the child is suspended during climbing or belaying.

The construction is designed to reduce pressure and improve comfort during extended climbing sessions, making the harness suitable for young climbers developing their skills on indoor and outdoor routes.

Adult-Style Climbing Features

Despite its child-focused design, the Petzl Macchu Harness provides practical features normally expected from an adult climbing harness. It has two tie-in points and a contrasting-color belay loop that makes it easier to visually check whether the belay device is correctly attached.

Two rigid front gear loops provide convenient access to quickdraws and other climbing equipment. A rear accessory loop can be used to attach a chalk bag, while detachable rear leg-loop elastic bands help keep the harness tidy and comfortable.

Recycled Materials and Compact Storage

Petzl incorporates recycled materials into the MACCHU as part of its eco-design approach. The exterior fabric of the waistbelt and leg loops is made from 100% recycled polyester.

The harness is supplied with a compact storage pouch made from 100% recycled polyester fabric, making it easier to transport and store between climbing sessions.
