Looking for waterproof frame/seatpost-mounted saddlebag

[Shut Up Legs]

As the title suggests, I need a saddlebag, preferably waterproof, although I'll wrap its contents in plastic bags if need be. I need to mount the saddlebag either at the front of the top tube (e.g. one of those triangular bags), or on the seatpost. A saddle-rail mount is not an option, because I now have a GoPro camera mounted on the saddle-rail with a K-Edge mount, but there is room below this for a saddlebag, particularly since I have lots of exposed seat-post, being a tallish guy. Suggestions, anyone?

Thanks for the reply . Not what I'm after, unfortunately, as it's just too heavy. I've been looking at the Vaude Cruiser frame-mounted bag, but I can't find any information on its size. Even the Vaude website doesn't specify its size. I need to know how long it is, because I want to fit the mini-pump into it if possible.
--> never mind, just found it: 27 x 9 x 6cm, and the pump I use on this bike is this one, which is 24.5cm long: http://www.topeak.com/products/Pumps/EinsteinDX, so will fit nicely .

See what you mean about hard to find the size of it. Amazon quote a size and has some reviews of it.

My toppeak aerowedge earned its money on the weekend, its waterproof and kept my S4 dry in torrential rain without mudguards!
