Matches that keep burning in wind and relight after being dunked in water.

A storm match is not a match with better coating — the head carries its own oxidiser, so wind cannot blow it out and water does not kill it. Hold one under a tap and it keeps going.

Twenty in the pack, each burning around twelve seconds, which is long enough to get tinder properly lit rather than just scorched.

Keep the striker dry. The matches do not care about water, but the striker strip does.
