How to tie the backpack straps diagram

Schoolbag backpack straps tie method:

1, first of all, the strap by the top of the two rings, from the two rings inside through.

2, over the bottom ring, from the top of the ring inside through, along with the original backpack straps together to pull down, schoolbag straps are tied.

The straps will be adjusted to their own comfortable length, not too long, so that the back of the bag as a whole and the back, the bottom of the waist, the waist belt should be adjusted to the length of the buckle, so that more than 60% of the weight transferred to the waist and crotch, so that backpack will be a lot easier.
