I do a light of fire lighting in the winter with the scouts. I really like my firesteel ferro rod. PJ cotton balls work great as well as does the Tinder Qwik.

I also like to keep birch bark and/or fatwood on hand. Fatwood is really great. Shave off a bit. Light your tinder which lights this bad boy and you should be able to get a fire going pretty quickly! Never had a problem with the cold / snow / wet conditions...
