A backpack includes a pack body, two shoulder straps extended from the pack body for allowing the wearer to wear the pack body at the wearer's back, and a suspension arrangement which includes a resilient unit provided between the pack body and the shoulder straps for absorbing a bounding force of the pack body. Therefore, the resilient unit allows a relative movement of the pack body with respect to each of the shoulder straps but minimizes the relative movement of the pack body by absorbing the bounding force of the pack body. The resilient unit is also arranged for evenly distributing a loading force of the pack body to each of the shoulder straps, such that the resilient unit absorbs the bounding force of the pack body at different directions so as to balance the uneven loading force at the pack body.

The backpack, as recited in claim 3, wherein said carrying system further comprises two strap slides provided at said lower ends of said shoulder straps to couple with said lower resilient straps respectively, such that each of said strap slides allows said lower end of said shoulder strap to be detached from said lower resilient strap and allows a usage length of said lower resilient strap to be selectively adjusted. 6. The backpack, as recited in claim 4, wherein said carrying system further comprises two strap slides provided at said lower ends of said shoulder straps to couple with said lower resilient straps respectively, such that each of said strap slides allows said lower end of said shoulder strap to be detached from said lower resilient strap and allows a usage length of said lower resilient strap to be selectively adjusted. 7. The backpack, as recited in claim 5, wherein said suspension arrangement further comprises a strap fastening unit for detachably coupling each of said lower resilient straps at said pack body, wherein said strap fastening unit comprises two first strap fasteners extended from said back pack and two second strap fasteners provided at lower ends of said lower resilient straps respectively, wherein said first strap fasteners are detachably and rotatably coupled with said second strap fasteners to detachably couple said lower resilient straps at said pack body. 8. The backpack, as recited in claim 6, wherein said suspension arrangement further comprises a strap fastening unit for detachably coupling each of said lower resilient straps at said pack body, wherein said strap fastening unit comprises two first strap fasteners extended from said back pack and two second strap fasteners provided at lower ends of said lower resilient straps respectively, wherein said first strap fasteners are detachably and rotatably coupled with said second strap fasteners to detachably couple said lower resilient straps at said pack body. 9. The backpack, as recited in claim 7, wherein each of said first strap fasteners comprises first and second fastener panels defining a sliding gap therebetween and an engaging through slot formed at said first fastener panel to communicate with said sliding gap, wherein each of said second strap fasteners comprises a sliding panel slidably inserted into said sliding gap and a resilient engaging member flexibly protruded from said sliding panel to engage with said engaging through slot when said sliding panel is slid into said sliding gap to detachably couple said second strap fastener with said first strap fastener, such that said first strap fastener is detachably and rotatably coupled with said second strap fastener. 10. The backpack, as recited in claim 8, wherein each of said first strap fasteners comprises first and second fastener panels defining a sliding gap therebetween and an engaging through slot formed at said first fastener panel to communicate with said sliding gap, wherein each of said second strap fasteners comprises a sliding panel slidably inserted into said sliding gap and a resilient engaging member flexibly protruded from said sliding panel to engage with said engaging through slot when said sliding panel is slid into said sliding gap to detachably couple said second strap fastener with said first strap fastener, such that said first strap fastener is detachably and rotatably coupled with said second strap fastener. 11. The backpack, as recited in claim 1, wherein said pack body has a storage cavity, a top opening, an enlarging slit extended from said top opening to enlarge an opening area of said storage cavity, and an enlarging fastener provided at said enlarging slit. 12. The backpack, as recited in claim 4, wherein said pack body has a storage cavity, a top opening, an enlarging slit extended from said top opening to enlarge an opening area of said storage cavity, and an enlarging fastener provided at said enlarging slit. 13. The backpack, as recited in claim 11, wherein said pack body further comprises a partition wall provided in said storage cavity to partition said storage cavity into a front cavity and a rear cavity as two discrete cavities that said top opening only communicates with said front cavity, wherein said an enlarging slit extended from said top opening to enlarge an opening area of said front cavity. 14. The backpack, as recited in claim 12, wherein said pack body further comprises a partition wall provided in said storage cavity to partition said storage cavity into a front cavity and a rear cavity as two discrete cavities that said top opening only communicates with said front cavity, wherein said an enlarging slit extended from said top opening to enlarge an opening area of said front cavity. 15. The backpack, as recited in claim 13, wherein said pack body comprises a back panel, a front panel, two side panels, a bottom panel, an opening cover foldably extended from said rear panel to said front panel for covering said top opening, and a cover locker releasably coupled said opening cover at said front panel, wherein said cover to locker comprises a first locker member provided at a front edge of said opening cover and a second locker member provided at said front panel, wherein said second locker member is sidewardly and slidably engaged with said first locker member. 16. The backpack, as recited in claim 14, wherein said pack body comprises a back panel, a front panel, two side panels, a bottom panel, an opening cover foldably extended from said rear panel to said front panel for covering said top opening, and a cover locker releasably coupled said opening cover at said front panel, wherein said cover locker comprises a first locker member provided at a front edge of said opening cover and a second locker member provided at said front panel, wherein said second locker member is sidewardly and slidably engaged with said first locker member. 17.
