I got my Jandd Frame Bag back in November (First Look - Jandd Frame Pack) and it has lived on my Norco CCX for most of the time since then. Its well constructed from Dupont Cordura, a pretty damn tough material. It features two pockets, the right side zipper opens up into the large main pocket, big enough for spare tubes, pump, tool, first aid kit, keys, cell phone, and a few other bits. The left zipper opens into the flat pocket great for holding maps or other flat-ish items. The total capacity is about 3 liters and the bag weighs under 200 grams. The zippers are tough too, you can easily open and close the pockets while still riding your bike.
The bag comes in a variety of different colours to suit your tastes. It has extra long straps to adapt to whatever frame configuration you have, then cut the straps to length and cauterize the ends. My frame bag has been covered in mud, soaked in water, sweat on, dripped with snot (ewwww) and still looks great. its a damn tough all purpose gear bag. I might just buy another for my mountain bikes.
