I have really bad luck with flats. I carry a hydration pack without the bladder:
1 extra Sportsdrink
3 Tubes
1 Flat kit
2 Multi-tools (one, traditional bike and one that converts to a knife and pliers/wrench)
Saddle rack that hold two additional bottles and 4 c02 cartridges
1 Mini-pump on frame boss bracket
2, 200 lumen flashlights
2, GoPro cameras
1 Armadillo Tire (yes, the whole damn thing)
1 Compact vest
1 Mini speaker
1 Mp3 player
1 wallet
2 Keys
1 Cellphone
Various pills and drugs
