Beware of the so called waterproof matches that require the special striking surface.
On a couple of types I have tried over here, while the matches are waterproof, the striker surface is not! The ones i am thinking about come in small white bottles like pill containers with the stricker surface the exterior of the lid. I found that when it got damp, the surface tended to disintergrate/dissolve leaving you unable to use the matches.
If you use these it may be worth checking before you come to depend on them..
Get a BIC. Keep it warm and dry in a zip-lock in an interior pocket. Or one of those magnesium striker bars. Nothing else is reliable here in wet Alaska.
