Surviving Arctic Temps at the Mammoth Sniper Challenge – Gear Tasting 71

Surviving Arctic Temps at the Mammoth Sniper Challenge – Gear Tasting 71

On today’s episode, Bryan gives a recap of the recent Mammoth Sniper Challenge and how his gear performed. Due to the temperature dropping to a low of -2° during the event, the challenge became not only one of performance, but also survival in harsh conditions.

Bryan also provides some helpful lessons learned about prepping and maintaining gear during such low temperatures.

In each episode of Gear Tasting, Imminent Threat Solutions Editor-in-Chief Bryan Black answers your gear-related questions and shares his insight into what we’re currently evaluating at ITS HQ.

For more on the gear we review, check out our GEARCOM category here on ITS.

Maybe I missed the boat on this, but I would really like to see a review of some woobies. Some companies like Kifaru International have some pretty pricey...I mean nice looking ones and even a version I hadn't seen before. The doobie!

Tip for water in cold environments. Make sure you use a wide mouth bottle, ie nalgene, ensure about 1/4 of water in it, put about 2 hand fulls of snow place in day pack/rucksack and start walking. The movement of water back in forth in a partially filled bottle will cause the snow to melt, only works till you've hit about 3/4 full, after that not enough room for movement of water and snow. I used this all the time on EX and in the high Arctic with the military.

For the fuel canisters to function properly, there has to be enough pressure to push sufficient gas to the stove.  The pressure in the canister causes most of the fuel to be in the liquid phase, though some has converted to the gas phase.  For the liquid to evaporate to the gas phase there must be sufficient energy (heat) present.  This is why the canister feels cold to the touch when in use.  Under cold temperatures the fuel would be more liquid phase and less gas in the canister.  This results in a lower pressure on the gas and thus a less fuel reaching the burner.  That is the basic explanation, without going too deep into the science (and I would need to dig out my old textbooks to explain it in more scientific terms).


I have seen a stove and canister system that is designed to work in warm and cold environments.  In warm weather the stove sits on top of the canister.  In cold weather the canister is used upside-down and there is a short hose to take fuel to the stove.  Unfortunately, I can't remember what it is called.

Fantastic post. This is usable D.O.P.E. for folks considering something like this. Thanks much for sharing.

It's been a couple years since I've had to buy fuel canisters, but I believe there is a low temperature fuel mix available. It would be interesting to see a side by side comparison boil test in low temperatures.
