This is kind of cool. The styling comes off pretty aggressive though.
And then you pick and choose which pockets and accessories you want to include:
Seems like the large would be a great size, and you can choose exactly the kind of pockets you want. You can even mount small pockets on top of large pockets.
Only problem is it gets pretty damn pricey. The pockets and accessories are not cheap...$50 for each side pocket, more for the larger pockets.
Don't know how hard it is to swap pockets on and off, but it would be cool if I could keep my bicycle bits (tools/pump/tube/mini u-lock/etc) in one "tool pocket" and swap it on and off depending on whether I am on the bicycle or the motorcycle. Right now I have to dump a bunch of junk out on the floor every time I switch uses (if I don't want to carry extra stuff).
edit: they also have two other models on the same system. One small one that only has 2 accessory rails (so it looks cleaner, but you can't get a large size) and another one that comes in small and large but has 8 accessory rails so you can really load it up.
