Winter camping can be a fun experience. You can experience the outdoors in a whole other way. The smell of pine trees and seeing snow-covered peaks are an experience that can only really be had during the colder parts of the year. Hiking in the snow, ice fishing, and building a campfire to keep off the night chill can be unique experiences.
Of course, camping in the wintertime it also has its own set of challenges. The colder temperatures, which will become even colder at night, can pose a real danger to campers. To keep the cold at bay, it is important to know how to properly insulate your tent.
Proper insulation will keep the cold away. Insulation is a two-way street; it keeps the cold air out and the warm air in where you need it. There is a real danger of hypothermia in cold temperatures, so making sure how to do this properly will ensure that you have a safe winter camping experience.
Winter Camping Gear
There are some essentials that every cold-weather camper needs to have. The following items should be part of your winter camping gear.
- Closed-cell foam sleeping pad
- Sleeping bag with a lower-limit temperature rating
- Synthetic or wool base layers
- Socks, gloves and a cold-weather hat- these will retain body heat.
- Healthy snacks with lots of nutrients
- Stainless steel water bottle with a bottle insulator
- Reusable straws- these will reduce the chance of spills on your clothes or gear.
- Tent Brush
How Body Heat Works
The most important key to survival in a cold-weather environment is to maintain your body heat. If your body temperature becomes too low, you can run the risk of hypothermia. Luckily, the human body has several ways that it regulates body heat.
One way that our body maintains its temperature is through sweating. As we workout our body sweats and this moisture evaporates on the skin surface, cooling our bodies. However, as clothing becomes wet as the moisture has nowhere to go, which will lower the body temperature. As a result, in cold weather, it is important to not overexert yourself.
Radiation is the process of heat leaving the body. Too much radiation of our body heat can cause a lowering in body heat. Therefore it is important to wear clothing that will trap in heat.
Sleeping on the cold ground can cause conduction through body heat. The ground will absorb the heat from the body, therefore cooling it. Because of this, it is important to have a protective layer between your body and the ground.
We can also lose body heat through convection, in which vapor escapes from a heat source. Our bodies lose heat from areas such as the head in this way.
It is important to protect your body from the loss of body heat in cold weather. This is done in both the way we dress and insulate our shelter.
Insulating for Winter Camping
- Reduce ambient Space in your tent
- The less open space in your tent, the more heat is trapped
- If you are camping with more than one person, put your sleeping pads as close together as possible. You can also use coupler straps to connect your sleeping pads together.
- Place gear and backpacks around the perimeter of the tent to further insulate the inside of the tent.
- You can also use body warmth with your partner to cut down on the surface area exposed to cold air.
- Remember, you only have the four walls and the floor of your tent to insulate, so your own body heat can help to keep you warm.
- Dress Appropriately for the Cold
- Sleep in base layers to keep warm while sleeping in temperatures below 30F.
- Avoid tight-fitting clothes that can restrict blood flow.
- Do not dress too warm, as trapped moisture will lower the temperature as your body cools off.
- Wear warm socks, fingered gloves, and a warm cap.
- Synthetic fibers or wool are your best choices as they will allow your body to breath will still trapping heat. These materials are moisture-wicking and will redistribute moisture better for evaporation. Cotton absorbs moisture, so it should be avoided for cold weather.
Sleeping Bags and Sleeping Pads
Sleeping bags only offer so much warmth. Even “warm” sleeping bags have their downside once temperatures drop too low. The best protection is to have a sleeping pad underneath the sleeping bag. These aluminized foam pads help to add insulation as well as conduct more heat for you while you sleep.
If you wish to use an air mattress, you can also place the pad under the mattress to increase comfort and insulation. Some experts even suggest placing the pad on top of the mattress, in between the mattress and sleeping bag.
Make sure not to burrow or breathe inside your sleeping bag. Condensation will lower the insulating ability of the sleeping bag, and will cause issues with keeping it dry. Instead, cinch the draft collar and close the hood around your nose and mouth allowing for a hole to breathe out of.
To add warmth to your sleeping bag, use a stainless-steel insulated water bottle filled with hot water. Place it at the foot of your backpack and the radiating heat will warm you during the night.
Insulating Your Tent
Insulating the surface area of your tent will help in trapping the warm air and keeping out the cold air. As most of the warmth in your tent is going to be based on the air in your tent, keep in mind your surface. Think less is more when picking the tent to take. The smaller the tent, the easier and more effectively you will be able to insulate your tent.
Most of the cold air is going to enter your tent through the walls of the tent. For this reason, you will want to trap as much warm air as possible. Using reflective foil to line the walls of the tent is a good strategy to use.
Placing the reflective foil on the inside tent walls and roof will reflect the warm air back down as it rises. However, the interior method can be time consuming and has to be repeated each time you set up your tent.
You can also use a reflective blanket attached to the roof of your tent. Attach it with the reflective side down so that the warmth from your body heat will be bounced back to you. These blankets are also useful for emergencies, so pack more than one, just in case.
To insulate your tent from the outside, you can use a simple tarp to cover the roof of your tent. It will provide several benefits to you. It will keep dew, frost, and snow from forming on your tent. It will also aid in trapping the heat in your tent.
A good tarp can also be used as a windbreak outside your tent. You can prop it up against the direction the wind is blowing. This will cut down on the chilling wind blowing at your tent and possibly lowering the air temperature in your tent.
You can also insulate the floor of your tent with reflective foam, which will help to insulate the area inside the tent by reflecting the heat from the ground back into the space. You will want to do this early in the day if at all possible. Once the ground refreezes later in the day and into the evening, it will be harder to create a flat surface to sleep on.
For the floor make sure to use double-sided reflective foam. This will allow your body heat to be reflected back to you, while also reflecting the cold air back to the ground. The foam should go to 5 inches up the walls to reduce air currents. If you do not want to sleep directly on the ground, use an air mattress to reduce air space.
If you are not a DIY insulator, you can buy a four-season insulated tent. Make sure the tent says it is insulated before you purchase. These tents can run on the expensive side, with prices ranging from $500-800. However, if you plan on doing a lot of multi-seasonal camping, this could be a good investment.
Tent Heaters for Tent Camping
Heating the inside of your tent is a great way to keep warm. While a campfire is a good way to stay warm while sitting outside, you can’t bring one in, for obvious reasons. Also, you do not want to leave a fire burning outside your tent overnight with it being unattended. While you are able to trap some of the warm air by keeping your tent door open, this is not an effective way to heat your tent.
There are some safe heaters that you can use inside your tent. One option is electric tent heaters which require an electric source to work. Unless you are packing an electric generator, these outlets will only be available at RV campsites.
Propane heaters do not require an external power source. They also are designed to emit heat without a flame, which makes them safe. One caution is that propane does emit CO2. If using a propane heater, make sure to open vent flaps or gaps to allow the CO2 escape.
No matter the heat source you choose, always practice caution when using one. Never leave a tent heater on unattended to avoid the chance of accidental fires. Also, never go to sleep with a propane heater on. Heat your tent, and then turn the heater off before turning in for the night. You do not want to run the slight risk of carbon monoxide poisoning.
Winter Camping Tips
- Pack high-calorie snacks. Your body will need fuel, especially at night to keep warm. Eating foods with lots of carbohydrates, sugars, and fats are good choices. Protein bars, such as Clif bars are wise choices. Chocolate, cheese, and nuts are good choices as your body will metabolize these slowly giving you more fuel through the night. Having a warm meal before bed helps this process as well.
- What do you do when nature calls at night? Stepping out in the cold is not always going to be desirable, especially as temperatures drop. Men may want to designate a pee bottle (mark it so you and your fellow campers know which one it is). Pee funnels can be purchased for women (a wide-mouth jar can be used as well).
- Staying hydrated is important in cold weather. Keep your water bottles insulated to keep them from freezing. Insulation will also keep liquids warm, which will, in turn, keep your core temperature up as well.
- Check operating and charging temperatures of electronics. Extreme temperatures can permanently damage electronics. Store them in the foot of your sleeping bag to keep them from freezing.
- Make sure to have something to cover your head. We lose most of our body heat from our heads. Having a nice knit cap or balaclava will help to not only trap in your body heat, but it will also keep your ears warm and aid in a better night’s sleep/
- Try to set you tent up against a natural windbreak. These can be a rock formation or shrubs. These will reduce the chilling wind from blowing through your campsite. You can also stake part of our tarp to use as a lean-to to help to trap warm air and keep out the cold.
- Heat packs are a great tool as they are easy to keep in your pocket and in your sleeping bag. They also are easy to reheat by exposing to air and shaking them. Such brands as Hot Hands as cheap and effective ways to keep warm.
- Make sure that you are informed of the weather conditions where you will be camping. Pay attention to what the temperature will be. Also, be aware of any weather systems moving through the area. You do not want to be going out into the wilderness expecting at most a light snow, and become trapped in a blizzard.
