I make sure I always have some matches lying around in my jacket and my backpack. I also make sure I always have matches in my backpack in a place where I can find them. I often use the matches found in the American MRE rations. ( just your usual damp weather matches in a matchbook with a striker) to back things up I have a waterproof bag with the , better, storm matches found in the Britisch MRE rations. next to that I have a normal firelighter with me. but it happened more than once that the button got pushed in whilst in my backpack so that my lighter was empty and my backpack full of gass. mind this. if you stuff your bag to hard, all the stuff might push the firelighterbutton so it empty's itself.
I also always have a magnesium stick with me.
as for the matches in an industrial produced waterproofmatchbox... I never use them because I can't see why a good waterproof bag doesen't play the trick. and its lighter.
How many of you guys ( and girls of course) take pieces of rubber innertube with you. it seems to be a good way to light a fire in damp conditions, but is it very bushcrafty?
