Cold weather means everything takes longer. Anticipate and plan for the extra time needed. Be realistic when it comes to hiking mileage.
Stop to rest when hiking. Excessive sweating and non-wicking clothing will make you colder.
Protect exposed skin and lips with lip balm (SPF 15 or higher) and sunscreen (SPF 30 or higher). Check EWG for the best-rated sunscreen and lip balms.
Drink plenty of water daily, generally 2-3 quarts. You will not realize how dehydrated you are during the winter since the air is drier and sweat evaporates before you know it. Consume your water by eating soups and other brothy meals, and make hot beverages such as cocoa or cider at night. Warm drinks (and food) benefit the body by warming you from within.
Carry a wide-mouth water bottle. To prevent the top from jamming with ice, carry it upside down in your pack. Water will freeze at the top, and when you turn it right side up to take a drink, you will have water instead of ice. Store water bottles in your sleeping bag or wrap a cozy around them to prevent the water from freezing. You can also bury them in the snow. Snow is a good insulator.
To prevent your Camelbak from freezing, blowback any water left inside the hose into the bladder after a sip. The water hose is the first thing that freezes. Remove your hydration unit from your backpack at night and put it near your sleeping bag.
Insulate by layering clothing with the outside layer being wind-proof. Three layers will cover most outdoor conditions. When it is freezing, you may need up to four layers, but often, three is enough if using a heavier-weight mid-layer. If it is less cold, you will need only two. Hiking rule of thumb: if the temperature is less than 20 degrees F, you will need all 3 layers (up to 4 or heavier mid-layer when it gets below 0 degrees F). If the temperature is between 20 and 50 degrees F, you can usually get away with 2 layers: a wicking base layer and an outer layer. You will be cold starting with two layers but will warm up once you get moving. When adding layers, any successive outer layers should be larger than the inner layer; otherwise, the outermost layer will compress the inner layers and decrease the insulation properties of the clothing.
Never wear a single heavy garment when hiking in the cold, even if it is heavier than the combined weight of the layers. A single layer does not insulate.
Do not wear cotton, silk, or down. These fabrics are unsuitable for outdoor activities because they do not wick away moisture. Instead, they readily absorb water and, when wet, lose almost all their insulating qualities. Cotton, in particular, readily absorbs sweat and does not dry quickly. The moment you rest, it will leave you feeling dangerously cold. Ditch all your cotton gear, including socks, shirts, underwear, and pants. One last disadvantage of using cotton for packing is its weight and space. It is bulky and heavy for packing..
Underdress for the temperature. You may feel a bit cold at the beginning of your activity, but after a couple of miles, your body will generate heat and warm you up. Always take extra clothing for layering and use it when you need it.
Cover your head. We lose a fair amount of body heat from our head – anywhere from 10 – 30%. Wearing a hat that covers your head and ears helps prevent heat loss due to radiation. Look for insulating, wicking fibers. Wool and fleece are both excellent.
Cover your mouth while moving. Respiration from breathing in the cold air also results in heat loss. Covering your mouth and nose with a bandana, balaclava, buff, or scarf will trap dead air and allow it to warm up before breathing in. This will significantly improve respiratory comfort by increasing the warmth and humidity of the air before entering the lungs.
Cold hands or feet signify losing heat from your head or torso. Keep your torso warm by layering or adding a hat. A warm torso allows your body to maintain warmth (blood flow) to your extremities.
Cold feet can be caused by improper shoes/insoles. Feet are subjected to conductive cooling through the soles. Replace worn insoles with wool/acrylic felt or fleece for the most warmth. Another option is to add thin sock liners underneath your insulating socks. Make sure the sock liners are thin. You don’t want the shoes to be so tight that it cuts off blood flow to the feet.
Use your head as a thermostat. Because 10-30% of our heat is lost from our head, removing a hat or putting one on makes it easy to regulate core body temperature.
Wear Mittens instead of gloves. All things being equal (the type of fabric and insulation), mittens are the most effective way of keeping hands and fingers warm. Layering also works when it comes to insulating fingers. Add a thin, tight-fitting polyester (or wicking) glove underneath your mitts or gloves if they are not warm enough.
Conserve body temperature. Did you get hot while hiking and remove a clothing layer? If so, put this layer back on as soon as you stop moving; this will conserve your body heat.
The most fundamental way to keep your core warm is to eat – often. Food calories generate heat in the body to keep you warm, especially fat, which offers the most calories per weight (9 calories per gram). The best fats to consume are nuts, seeds, and plant oils. See also backpacking foods to eat when it is cold outside.
Pitch your tent in a spot that protects it from the wind.
Put on dry socks and clothes as soon as you finish setting up camp. Put any wet socks inside your sleeping bag to dry.
Know the route to the bathroom before dark and look around for any dangers around your campsite. Invariably, you will have to get up at least once at night and want to avoid accidentally stumbling into holes or water in the middle of the night.
Refrain from cramming too many people/creatures into a tent. More bodies equal more breathing and less ventilation, thus more moisture/condensation. Your tent should be large enough to move around comfortably and store winter gear, which is bulkier.
Insulate your body when resting and sitting to prevent heat loss by conduction. Use your sleeping pad when sitting to eat or rest. A closed-cell foam pad provides the most insulation (R-value). If you prefer to sleep on an air mattress, place a liner underneath it for better insulation. A foam pad, while bulky, can be used as a liner under the air mattress and is a good backup if the self-inflating pad gets punctured. The foam pad can also double as a cushion and insulator when sitting.
Rather than covering the entire underneath of the tent with a ground cloth, you can keep your sleeping bag dry by making a waterproof liner (tarp/heavy garbage bag – cut to size) and placing it underneath your sleeping pad. An old shower curtain liner also works well as a bag liner (or ground cloth) and is very lightweight & cheap.
Get a sleeping bag rated 10°F lower than the coldest temperature you expect to camp in. There is no reason to have more than one sleeping bag rated for different temperatures. During the warmer months, use the same bag and open it up for ventilation, or sleep directly on it.
Bring tomorrow’s clothing into your sleeping bag to stay dry and warm. Keep your clothes or socks away from a fire if your clothes
Put removable shoe insoles inside your sleeping bag at night to prevent cold feet in the morning. If it is freezing and you fear your shoes/boots may freeze, put them inside an inverted stuff sack and bring them into your sleeping bag.
Drink hot, nonalcoholic, and noncaffeinated drinks before going to bed. A warm drink increases your body temperature and delivers psychological benefits. Since caffeine is a diuretic, it will pull water from your body, and you’ll have to pee in the middle of the night. Alcohol speeds up heat loss by dilating the blood vessels near the skin’s surface.
Get into your sleeping bag when you are warm. Don’t expect the sleeping bag to warm you. It can, but you’ll be ahead of the game if you are warm when you first climb into the bag. If you’re not warm, drink hot liquid before bed or start moving once you get in your bag by violently kicking your legs to generate heat. If you have spare space at the bottom of your sleeping bag, fill it with dry clothing. Filling extra space will reduce the area your body must heat.
Eat a hot meal for dinner. When boiling the water for dinner, add extra water to your cook-pot to fill your Nalgene. Place the hot water-filled Nalgene in your sleeping bag to warm when you get in and keep your feet warm. You’ll also have non-frozen water to sip on in the morning or to pour in your pouched cold-cereal.
Cover your head and ears when sleeping with a beanie. With your entire body zipped inside a bag, your head and face are the body surface areas where heat can radiate away.
Bring extra batteries for electronic devices. If you are on your last battery, switch the batteries around or remove them from the device so they don’t get turned on by mistake and drain.
Warm up batteries before using them. Nickel-cadmium batteries are rechargeable and work well in the cold.
Wear latex gloves when washing dishes.
Take care of your feet, always! They carry you where you want to go. Wear correctly fitting shoes and bring extra moleskin or adhesive bandages in your first aid kit.
Bring a space blanket, just in case. These foil blankets weigh and cost almost nothing and can make a difference between life and death.

These are some really useful tips for winter camping.
Use hand warmers... in your hat.
Don't overdo the layers on your extremities.
Sip a hot drink before bed and use the leftovers as a hot water bottle.
I thought that sleeping totally inside of a sleeping bag, body and head as well would lead to carbon monoxide poisoning cuz the CO we exhale doesn't vent quick enough. prove me wrong if ya can
the USGI sleeping bags have implicit instructions to only cover the head with the bivy, and to keep head exposed
The key is how you dress. Multiple layers and staying dry is most of it. Rain jacket suffices as an outer layer to keep dry. I prefer it over a bulky winter jacket.
Put warm water into your drinking bottle and use it as a hot water bottle in your sleeping bag to stop your water freezing and make it snug and warm in one area at least, when you get in!
