Years ago, I started filling empty snuff (Skoal/Copenhagen) cans with bits of those artificial firelogs. Packed full with the lid on and electrical tape to seal the lid, these things will last for years in your hunting gear. They weigh next to nothing and it only takes one match to get them ignited. They will also burn plenty long enough to get a good fire going. I recently tested one that I've had for 10 years, and it worked perfect.
