Delivering all the sleek style benefits of a relaxed roll-top backpack, with the addition of waterproof PU-coated fabric, this is where fashion meets function. This is a must for those who commute on foot or by bike, complete with a waterproof main compartment, so things like technology and paperwork stay dry and protected, whatever the weather. Also available in a larger version (QS575), this streamlined bag offers a more compact silhouette for practical, contemporary styling.
