regardless of the decision that lead to the situation ... anyone can find themselves experiencing hypothermia should they make a mistake (and EVERYONE makes mistakes)
what can you do once it gets cold and wet?
- clothes ... you can survive being cold, you cant survive being wet and cold ... take off the wet clothes and get into a waterproof shelter or bivy when stopped ... if you can keep moving, have a WPB jacket, for 6 oz and 100$ (OR Helium) theres no excuse not to carry one... have clothes that are quick drying ... items like fleece that have a fuzzy interior you can wear damp as the moisture is much reduce over the skin, rather than stuff like wet base layers which simply seep the heat out of you ... a wet synthetic jacket aint the best, but you can put it OVER you WPB jacket an still get some insulation ...
- shelter ... bivy bag, bothy, garbage bag, whatever ... you simply need to get out of the rain and preserve our heat ... in emergency situations a tight enclosed space works better than a tarp as you save heat and it works as a vbl ...
- fire ... a highly neglected skill ... ill simply ask when was the last time you practiced starting a fire when its pouring rain or in heavy snow ... its quite a bit different from doing it in ideal conditions ... if you cant start one in adverse conditions, dont make the assumption you can ... youll need a good knife to shave the wood, some kind of cover, an utterly reliable long burning firestarter, and a LOT of practice ... because the moment you need it most youll be borderline hypothermic ...
- stove ... in winter or in groups an UL canister stove if a fire cant be started ... boil the water, put it in a hawt nalgene or even a metal cup/bottle which is usable over a fire (either of which many BPLers say serves no purpose cause its heavy) and use that to warm you up ... dont bother with alchy or esbit, or other such ... when your shivering you want KISS and fast boiling ...
- heat packs ... you can carry a 12+ hour heat pack for an emergency ... combine that with an emergency bag and youll likely survive a night ...
- blizzard bag ... the us/uk army, uk sar an other agencies use this for hypothermia treatment ... it is simply a rated 40F sleebing bag and WP bivy combined that weights 360g and cost 40 bucks ... when you cant start a fire its gold, its that simple
- in the longer run have SYSTEMS that prevent a hypothermic situation ... synthetic clothing or quilts can help reduce the chance of insulation loss (especially when the sun dont shine for days or weeks, which many BPLers cant fathom), a hawt nalgene is a proven life saver in adverse conditions, a clothing system where you sweat minimally (eskimos know that sweat kills in winter), etc ...
all of this weights more of course ... and NONE of it can be learned by reading the intrawebs or even this post ... you NEED to go out and practice these SKILLS ... in your back yard, in the park, on a short daytrip, etc ...
