Question: Alien expanding seat bag
 

Amazon has a few reviews, but I was wondering if anyone here has it.

My commuting bike's seat bag is slightly too small. I need a little bigger one and this has expandable bags on the side as a "just in case" is a really cool idea.

Won't the side bag get in the way when you pedal?

That was exactly what I was thinking and trying to find out. :) The reviews say its not bad...but....I don't see how that can't get in the way. Even a slight rub on my legs when pedaling throws off my rhythm.
