Marathon is proud to be the UK’s only manufacturer of backpacks which are endorsed for their ability to protect children’s backs.

Chiropractors’ Association of Australia
The Chiropractors’ Association of Australia (CAA), together with Spartan* and Macquarie University (NSW) joined forces to research and develop the ChiroPak. This durable, functional and comfortable backpack is proven to reduce the incidence and severity of neck and back pain associated with the carriage of heavy loads.
The ChiroPak is the only backpack endorsed by the CAA.

Australian Physiotherapy Association
The Australian Physiotherapy Association (APA), together with Spartan* and the University of South Australia, joined forces to research and develop the PhysioPak. This backpack is proven to minimise harmful postural response and significantly reduce associated back pain, neck pain and minor spinal injury.
