Musette?

Sorry.

Have you tried a carradice saddle bag with one of the quick release fittings? Then no back problems no wide panniers and quick to get on and off. I think they look classy too. Not what your asking I know but I thought I'd throw it in there.

Fair play. I am after something minimal though. I thought a musette might have fitted the bill. As I say I don't have that much kit to carry but I don't like stuffing it in my jersey pockets. Other suggestions welcome.:)
