I've risked it for almost a year and left my flat kit at home... but then i got a flat and had to walk a couple of miles before I someone tossed me a spare tube!! I want to avoid that ever happening again but I'm unsure of how to carry all that stuff. On my road bike i use a saddle bag, but i've never seen anyone use one of those mtn biking. Also, I don't always take a camelbak with me riding.

How do you carry a spare tube and flat kit?!
