I have a tiny wedge bag, but it's exactly big enough for patch kit/levers/small multitool -- I can't even add my cell phone or a sandwich. Any recommendations for something that's just a little bigger? Everything I keep finding is either the same size as the one I have, or it's huge.

Something that actually holds a blinky up without it drooping to point at the road would be a bonus.

(I don't like riding with stuff in my pockets, so while I know stuff could go there, I'd rather not.)
