This rollable laptop backpack is one of the easiest and one of the best. Competitor is a Pearl-rolling backpack but offers no lifetime warranty. I already have a time to replace an ordinary backpack from Targus and me a new backpack was doing without hesitation sent. The Ruckack offers many different storage options incl. Zip, partially particularly soft padding, eg for scratch-sensitive smartphone displays. The mechanics convinced the water repellent material makes me rolling backpack in the rain without hesitation that my laptop can be wet, strutting behind me. The dirt protection is intelligently solved, but could still be a little wider, to keep even larger contamination of the rolls from the back. However, it is all in the context, I am very satisfied and recommend this rolling backpack without hesitation.
