Chile Pepper mentioned it's a lot of stuff. It sure looks that way, huh? Once it's rolled up (the black thing with purple trim is a tool roll), it's small. I was surprised at how much stuff can fit in that seat bag! I doubt I'd need the wrench or even the multi-use tool, however since it all fits and there's still room I just left it all together.
The bag is also expandable with a zipper around the top.
