The human spine is made up of 33 bones called vertebrae, and between the vertebrae are discs that act as shock absorbers. When something heavy-such as a backpack filled with books-is incorrectly placed on your child's shoulders, the force of that extra weight can pull your child backwards. To compensate, your child may bend forward at the hips or arch his or her back, which can cause your child's spine to compress unnaturally. Because of the heavy weight he or she is carrying, your child might begin to develop shoulder, neck, and back pain.

Ideally with a full pack on, the top edge of the waist belt should ride one inch above the top of the hip bone. Lastly, you should also pay attention to shoulder straps. These days many good quality backpacks are available in the market with adjustable shoulder straps. Backpacks with self-adjustable shoulder are regarded as top backpacks, because in these backpacks the shoulder straps can be rotated to accommodate individual neck and shoulder shapes.
The first thing you should look at is where you are going to use the backpack for. Outdoor backpacks come in so many specialized designs, there are hiking backpacks,fishing backpacks,backpacks for water sports and so on.

When on the other hand you need a backpack to go on a weekend hiking trip, you Will need the space to carry all the necessary items along. If your outdoor activities bring you close to water like kayaking or rafting, it's wise to look at a more waterproof outdoor backpack. So determine the usage of the backpack as well as the environment you are going to use it in.
