Prepared Minimalist

1. Wool Clothing: Wool is a natural material which keeps most of it's insulation properties even when wet. This fabric is fire resistant, arm, durable, and long lasting. I have 100% wool gloves, beanie, scarf, sweater, socks and vest around. People lose a lot of body heat from their head, and neck so it is important to cover them in freezing weather. On top of that, wool socks works great, and keep a second pair handy to swap out if your feet get wet. Treat your feet well or they will stop taking care of you (walking). I would also recommend a 100% wool blanket as well, but I haven't found one which is thick and under $200. Lastly, most wool that isn't made organically may be an issue for sensitive people. Some may think they are allergic to wool with rashes but more times than not it's because of the multitude of chemicals which are stuck in the wool fibers. I prefer Ecowool or an organic wool company. I have found the organic cotton and wool actually seem thicker and last longer possibly from a less processed way of making?
2. Layering: Layering clothes creates air spaces in-between each layer which helps regulate temperature. This allows one to take off one layer to keep comfortable. DO NOT SWEAT! Make sure you aren't too warm, or that can lead to lowering your body's temperature, which can lead to hyperthermia.
3. Heat giving items: In my past video of being ready for winter, I showed two types of heating options for hands and feet. To add to that list, there are electric blankets which they use a lot even in Japan to their Futons (floor bed mats).
4. Extra blankets & Fleece bedding: The thicker version of bed sheets which absorb some of the cool air from going through. KEEP BLANKETS IN YOUR CAR TOO.
5. Putting a insulation base to your sleeping ground: If one is camping or in a survival scenario, one can use leaves as a base so the ground doesn't absorb your heat. In a bed, you can either place a think blanket below, or other insulation. Carpeting in rooms keep warm air in as well.
6. Wind proof and water proof outer layer clothing: Moisture and cold can kill you you over time. A high MPR wind can send a chilling feeling up your bone. Having something which is wind proof is great to have on a windy day, while having something waterproof in the rain or snow is a must if you'll be outside for awhile.
7. Camp fires and candles: Fires run on oxygen and emits carbon monoxide. You run the risk of burning your home to the ground or suffocating with a fire on a table like a candle indoors. Make sure proper ventilation is met such as a chimney. Outdoors, make sure your tarp isn't near the fire, nor blocking in the carbon monoxide as well! If one is moving, you may like to hold fire in a fire bundle. (more on that later as well)

On the other hand, try to avoid...
1. Cotton: This absorbs water like a sponge and takes awhile to dry. I do admit I love cotton and still wear some during the winter, but I do have more wool and other alternatives. 
2. Not wearing a hat: Hats are said to keep in 80% more heat in your body which escapes from your head. 
3. Not wearing sunglasses: This may not keep you warm, but does protect you from snow blindness!
