The Petzl Macchu is a complete sport climbing harness designed identically to adult harnesses, except that it adapts to the growth of young climbers.
The waist belt and leg loops of Petzl's Macchu are designed with adjustment options so that the harness grows with the child, so that you no longer have to buy a new harness with each growth spurt. For comfort and support, ENDOFRAME technology (the same as on adult Petzl harnesses) ensures intelligent distribution of the climber's weight. This combined with the absence of compression or friction points in the waistband results in a much better level of comfort, so the user can concentrate on the climb without being distracted or disturbed by pain. The Macchu is for kids who are serious about climbing and want a harness they can wear as they grow and progress.
