(Continued from Part 2.)
Now you need to think about keeping your core warm, which is critical since that’s what your hypothalamus will focus on keeping warm if you start to get cold. No big surprise – start with merino wool or polypropylene long underwear top, then either a shirt, a turtleneck, a sweater/fleece or a combination, depending on conditions. I have an old Pendleton wool shirt that I received as a gift years ago that I absolutely love, and for sweaters/fleece I like the ones that have zippers in front so I can unzip to cool down. If I need to add some extra core warmth I usually bring a puffer-style vest that I can put on, and it packs down to almost nothing. Another alternative to a regular sweater that works well in some conditions is an Asbell Wool Pathfinder pull-over – its super warm and layers well. Asbell makes a lot of other nice wool products – check them out.
Once your core is warm you need to work on keeping it dry and out of the wind, which is where a jacket comes in. I tend to prefer uninsulated shell jackets that are good at keeping the snow/rain/wind off of me, so I usually go with some form of smock that’s long enough to cover my butt. My favorite is the Teesar Generation II Smock, which unfortunately no longer made, but there are great alternatives from Sarma, Arktis, Leo Köhler, and, if you’re feeling particularly rich, First Spear and Tyr Tactical. The reason I recommend a combat-style smock or parka is that they have tons of pockets, so you can access most of what you need without unzipping your jacket, wearing a chest rig or taking your pack off. Most of them have multiple pockets around the bottom that work great for holding magazines, plus other pockets for a FAK, fire-starting kit, flashlights, knives, etc. They’re typically light enough to wear as a 3-season jacket, but many work well as an outer layer in the winter.
Your outer layer should include a hood, since that’ll help keep your head warm and dry and keep the snow from getting down your collar. If you do want an outer layer with extra insulation the US Air Force N-3B Parka is still one of the best winter jackets you can find. If you feel the need for something camouflaged I’d recommend getting a winter camo poncho or over-suit, since you throw them on when needed.
Another possible option is a one-piece winter overall/snowsuit. These have the advantage of being very warm, and, since they’re one piece, they do a great job of keeping the wind and snow out. The disadvantage is that they make it harder to adjust your temperature if you start getting too warm – you can usually unzip the front and slide out of the top half and tie it around your waist, but it’s a lot clumsier than being able to take off a jacket. Another potential problem is they’re hard to get out of quickly if you’re having an urgent call of nature. Snowsuits are usually utilized when people have to be out in cold/snowy weather but don’t plan on performing a lot of strenuous physical activity, or those that need to be able to quickly throw something on over their regular clothing – examples include snowmobiling, mechanics, refrigerated warehouse workers, etc.Continue reading“Cold Weather Considerations – Part 3, by JM”
