Product Details

2017 new bags cheap Practical Adult Travel Trolly Backpack Computer Bag Waterproof Trolley Backpack

This ployester waterproof single trolley tube backpack features a drawbar inside the bottom of the backpack and a backpack strap on the left and right sides of the backpack. There is a roller at the bottom of the backpack that can be easily dragged on the ground. It can pull the crossbar with the lever and drive the strap to tighten or relax. The strap can adjust the length of the strap to avoid the wear and pollution caused by the excessive length of the outer strap during the dragging process. This design helps to reduce the size of the trolley and reduce weight.

The design of this  ployester waterproof single trolley backpack greatly reduces the damage that the backpack causes to the shoulders of the human body. It no longer needs to rely on the shoulder to bear the weight. So you can easily drag it with the lever. This kind of design is very helpful for workers, as well as students, those who have heavy loads such as computers in their backpacks.
