Toilet paper is bulky and vulnerable to getting wet in bad weather, .....That's why I have one of these http://www.facewest.co.uk/Ortlieb-Toile ... older.html

Blimy £22 for a loo roll holder

Another vote for WetWIpes, 'cos they don't turn into a ghastly soggy mess when rained on, as remarked on earlier, and are more versatile than loo-roll, too. WetWipes, as any parent will know, can do lots of jobs, including clean post punture-repair hands. They make a good job of doing the loo paper thing, too.
But my wouldn't-be-without item is probably my Petzl Tikka. Or maybe the Topeak multi-tool... or p'raps it's the PneuForce pump.
