15 minutes of fuckhot fire from one flare. (30 if you get the longer mil/law ones). Safe, easy to use, striker built right into the cap.
Double-bag them to make sure they stay dry.
If you've got the time/energy to kill, go ahead and spend an hour or two trying to get a fire going with bushcraft-tier methods if that suits your fancy.
If someone in my crew's going hypothermic and I need fire, out come the flares.
