The PJ saturated cotton balls seem to be the best bang for the buck in cold or wet conditions. A lot of them pack into a small space and you can use 1/3 of one all fluffed up to get damp tinder going in short order, even in soaking wet conditions. As a resident of the Pacific North Wet, I consider myself somewhat of an authority when it comes to starting a fire in wet conditions. The PJ saturated cotton balls take a spark better than the tinder that comes with a Sparklite or any other store bought creation, and they are dirt cheap to make. A trip to the dollar store will give you several years supply for two bucks. Throw in another buck for some sort of durable container and you are golden, although an empty shoe polish tin would be more than adequate
