checked out your RAVX bag at the website. NICE!

I second the idea to carry a COPY of your driver's license and insurance card. I keep mine in a small zip-loc baggie along with some money ($10-20) and what ever loose change accumulates. I have one on each of my bikes. Never have to worry about transferring back to my wallet after a ride. Hmmm - with 3 bikes I guess I have ~$50 stashed away. This way if I end up stopping somewhere to get coffee, snack, Sunday newspapers, whatever I always have enough to do it. When I get down to about $5 to $8. I replenish my supply.

So I took the batteries out of the ziplock and slid them into the pocket where the "skabs" are (pink pocket). I took the tube out of the box and slid into a recycled bulk spice ziplock, added 2 Neutrogena "Deep Clean Sport" wipes, travel size kleenex, chapstick.
I have RoadID on both my running and cycling shoes. My concern about keeping copies of driver's license, etc. is that I'll get complacent, leave them in the bag and if someone stole them it would be fodder for ID theft.
@Catrin, funny you mention the Arkel Tailrider trunk bag; my DH has one and I almost bought one yesterday. If I go on longer rides that don't need a pannier, but need more than a seat bag I'll get one.
What is a "jenni" wallet?

I put my spare in a baggie with cornstarch. Underseat bag has the spare, a couple of tire levers, CO2, multitool. I have handlebar bags (big and small, depending on where I'm riding/what I want to take), and use one to carry the cell and wallet.

Good idea to have copies of the DL and insurance card. When I buy another bike (sometime soon, I hope!), I'll do the same.

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.
