From the Manufacturer

The ever-so convenient and universally used top tube bag. Over the years, there have been countless requests for an Outer Shell version, and here it finally is. What took so long? Well if you know OS, you know it’s not like the others. Yeah, I’m different! No more flopping around. No more hard-to-access opening. No more figuring out if this bag will fit.

This is a strap-on and bolt-on bag all in one. A soft foam cover protects the bottom and covers the bolts (or bolt holes). It also comes with large washers, rubberized straps, and a rubberized bottom for a sturdy connection. Backed by a specially shaped plastic frame, this bag ain’t going anywhere.

What’s more, a unique separating zipper lets the bag open WIDE. It’s weather-resistant and has a cable port too. This little wonder packs a punch!
