Structurally, both are relatively the same, the only differences are in the Board of Atlas mount and the side pockets instead of the "bottle networks" from Factor. Even lacking a chest strap, which has a negative effect on eingeschnalltem skateboard on the wearing comfort.
The basic difference is in the processing. The Factor is high-quality, somewhat reminiscent of the Atlas tent. The "a mock laptop compartment" I will not guarantee entrust my notebook. A useful gimmick is also here the pocket for sunglasses.
Despite everything, the backpack fulfills its purpose. You get a lot pure (sweater, blanket, drinks - no problem) and can therefore be transported without worry a skateboard. As a school backpack I would not recommend it, but it was not designed. It's a simple backpack for leisure activities.
Anyone looking for a school backpack, should look at the Dakine Factor or similar, the back will thank it. When I look back remember the many books during my school days, I doubt that this model is long-lasting.
