Millton Backpack is designed for better protecting Children’s backbone. Nowadays, Children lead a busy life. Their tight schedule means that they need to carry their personal belongings : books, stationeries, GSM, water bottles, food, clothes, etc. all day long. In Europe, it is reported that a Spanish study (http://www.nhs.uk/news/2012/03march/Pages/rucksack-bags-back-pain-children.aspx.)  indicates that over half the children had backpacks exceeding 10% of their body weight and for those carrying the heaviest backpacks had a 50% higher risk of back pain than those carrying the lightest, and a 42% higher risk of diagnosed back problems.

Backpacks significantly disturb the posture and movement of Children’s bodies (especially their muscles and bones are under development). The mechanical explanation is that Backpacks create leverages on the torso which distort the natural curve of the spine. Consequently, it is stressful and energy wasting way to carry a load in the backpack.

To reduce the harm, the weight of the backpack must be dispersed onto the skeletal structure in a balanced way around the vertical axis so that the loading on the Children’s body is only vertically downwards. This creates naturally balanced and body friendly load carrying. To achieve this, all backpack weight must be held and pulled close to Children’s back, it is explained by Lever Principle. Millton backpack has 4 key design features to achieve a highly efficient weight distribution result:

1. Double metal strip to provides efficient two axis support for Children’s backbone by absorbing the force and impact from vertical and horizontal direction during Children’s agile body movement;
2. Double tightening string to hold and pull the backpack as close to Children’s back as possible;
3. External tightening mechanism to facilitate Children to further centralize backpack weight themselves and optimize the size of the backpack; and
4. Aeration design with Upper and lower cushion to serve as shock absorber for the contact point with Children’s back.

Other special feature:

1. Adjustable storage design to cater the needs to carrying different volume of objects (from a few books to a bulky jacket); 
2. Double layered cushioned materials to promotes comfort;
3. Resilient backpack bottom to enhance durability and protection objects inside;
4. Durable materials to achieve long product lifetime; and
5. Various testing process on straps length to ensure the backpack is suitable for different carrier’s size
