Seattle Sports knows about keeping your commuting or touring cargo dry...like...it is Seattle. With a large main compartment and a symmetrical design, these are great on the front or rear, either side. A 3-roll closure with compression strap and radio frequency welded seams means this thing could pretty much be floated down a river with your laptop in it and you'd have no worries. Lightweight and easily detachable, these panniers are also a nice middle-of-the-road size and can be pulled right off to take on foot.
