The patented shoulder pads reduce shoulder strain. A divider pocket has been added in front of the PC storage pocket, and a belt has been added so it can be attached to a carry-on bar. The fabric has been treated with water repellent. Purchased six months ago. I am selling it because I bought a larger backpack.
