Fire is one of the most important things you need in a survival situation outdoors (ever read Jack London’s short story To Build A Fire? You should). And sure, you have the skills to start a fire with a couple of sticks and your trusty survival knife, but wouldn’t it be nice if it didn’t have to be that difficult? Even if you’re not in a survival situation, it’s nice to get a fire started quickly and sit with a cold one and enjoy it. These fire cubes from S.O.L. (Survive Outdoors Longer) are waterproof and can get a fire going in any condition.
