Developed with top NZ adventure athlete Marcel Hagener, the new Marathon Magic Bodypacks fuse the biomechanics of comfort, balance and agility into cutting–edge simplicity. Rob Jarvis won the Atacama Desert Crossing in Chile using Marathon Magic 30.

With Omni Flow, U Flow and the Conus Clip chest strap, these are the maestros of body movement and pack stability - superb for adventure racers, cyclists, runners and fast walkers.

The stylish Balance Pouches on the 2 larger models are positioned for optimum arm swing when running. Each holds a 1 litre water bottle. You can access them with one hand when cycling and the flexible frame in the pack will bend with your body as you reach for the handlebars.

These packs won't "round out" when stuffed full like other adventure racing packs: they hug your body like a limpet under extreme movement. The Matrix Mesh harness keeps you cooler under maximum exertion.
