>>802450The only drawback to a lighter is in the frigid frosty freeze they fail (just because the gas condenses and you lose pressure). To a lesser extent elevation can be an issue if you're going high enough.
BUT not to worry! In summer I carry condoms to keep ticks and leeches out of my peehole. This isn't necessary in winter so instead I use the condoms to store batteries and lighters in my rectum to keep them warm.
