We all knows backpacks are the hot option for our life, as its easy to carry, release your hands, lighten bear load and abrasion resistant to attract buyers. They make our life more convenience for our life. A good backpack is long life and good feeling for shoulders. 

College backpacks are commonly used by college students, and are often preferred to handbags for carrying heavy loads or carrying any sort of equipment, or books because of the limited capacity to carry heavy weights for long periods of time in the hands. 

A pack frame, when present, serves to support the pack and distribute the weight of its contents across the body more appropriately, by transferring much of the weight to the hips and legs. Most of the weight is therefore taken off the shoulders, reducing the chance of injury from shoulder strap pressure (many backpacks equipped solely with shoulder straps can affect the posture of a person carrying more than *4 kg (*0 lbs)), as well as being less restrictive of the upper body range of motion. Most backpacks are capable of being closed with either a buckle mechanism, a zipper, or a dry-bag type closure though a few models use a drawstring fitted with a cord lock for the main compartment. 

A bodypack is a backpack fitted with one or more pockets that are suspended on the wearer's chest and loaded in such a way that the load in the front and the load in the back are close to equal. The majority of the load in a bodypack is carried by the hips. The ideal load carrying system should not disturb the wearer's natural posture, balance and maneuverability. The load must be dispersed onto the skeletal structure in an even manner, and should not produce unbalanced forces on the body.

Typical school backpacks generally lack the rigid frame and include only a few pockets in the front in addition to the main storage compartment. While traditionally very simple in design, school backpacks are often made with padded shoulder straps and backs as well as additional reinforcement to hold large numbers of heavy textbooks, as well as safety features such as reflective panels to make the wearer of the pack more visible at night.
