The UCO matches are a basic part of all my kits. REI also produces this type of match (probably same factory, just different branding). They do require the striker, which must be protected from moisture, but they work very well in all conditions that I have tried them (blowing snow, blowing rain, heavy rain). They will not extinguish even when dunked, lit, in water. You can play with packaging to fit you particular kit form factor.
