Just got a Deuter saddle bag, carry pump, tire levers and tube. It also has a pouch for a second bottle of water, and some energy bars fit inside, too. Once I get a bike computer, my phone would also go in there. I do not carry a multi-tool, never had a reason to. I will only take this on longer rides, shorter ones where I do not stray all too far from home I would leave it at home.
