When I'm off-roading, one of my pants pockets carries an Altoids tin fire kit that's secured with duct tape and a ranger band. The exact contents vary somewhat, but it generally holds an assortment of: char cloth, a candle stub, birch bark, fatwood, jute twine, pine shavings, horse hoof fungus, a tampon and some nuggets of pine pitch. It makes a great tinder bundle that I know I can rely on when it counts. It will burn for several minutes and the tin itself makes a mini hearth and windscreen.
In another pants pocket I carry a ferro rod and a BIC.
I discovered storm-proof matches last winter and they'll be in the pack forever more, too, when foul weather is in the forecast and frozen fingers make a BIC too difficult.
