A guy on a backpacking forum has asked the below. I recommended visiting this site so maybe he will chime in.

"Hi, I’m a Special Ed teacher at a small school on the edge of the Bristol Bay in Alaska. In the winter we sometimes travel by snow-go(snowmobile) or single engine planes. My school district has a rule that each child must carry a small survival kit around their neck while in transit.

Question–Does anyone have any suggestions other than the ones I see on ebay and amazon? I would prefer ones that had actual usable components. The old ones consisted of a trash bag sized tube tent and a 5 cent compass with a candle…..

Thanks in advance…"
