The whole thing weighs 2.5-pounds, costs $95 and comes -- fittingly -- only in black. As someone who has spent a lot of time on a bike in an urban area, I have to say that it all sounds very promising. Riding with a normal backpack on is fine, unless you want to stop and shoot something, in which case you have to take the whole pack off. The sling makes the process a lot simpler. Plus, the zip-around entry is nice because it's less likely to jangle itself open during a tough ride.
