That's very nice kit, ireckon. I like how it's built around that big candle. It should definitely buy you some time.
It might be worth a try to stage a snowboarding mishap under safe controlled conditions and put it to test.
I tested the kit in Tahoe at a ski resort two weeks ago when it was raining and somewhat windy, with snow on ground. Raining conditions is more of a challenge than snowing conditions in my experience. I was able to light the candle by using a Bic and a windshield made from my hands and jacket. I have heard that butane lighters (not Bics) have problems at high altitude. In contrast, I had no problem lighting a plain Bic at high altitude, but note that lighting a Bic in a wind is difficult.
I did not try to light the cotton balls, inner tube or trick candles. I figured those would be no more difficult than the candle. I also did not try to light a fire by using the ferro rod. Hey, I was mainly out there just to have some fun in the snow. I'll try the ferro rod next time. Maybe it will be easier than the Bic. Who knows?
