Wet clothes......sleeping bag????????????
Cold Weather Camping
1. REMEMBER: The sleeping bag doesn't heat you, you heat it. So use this rule, "Thickness is warmth", to keep in heat. If you're cold, add some more insulation (blankets, clothes).
2. DO NOT SLEEP IN BOTTOM OF BAG: Your breath contains water. If you close your bag with your head inside, then this water sticks to the bag. Wear a hat to keep your head warm.
3. CHANGE CLOTHES: NEVER sleep in wet clothes. Even perspiration will chill you at night.
4. EAT A CANDY BAR: This increases your metabolism (moves your blood faster) and it helps keep you warm.
5. GO TO THE BATHROOM BEFORE BED: This saves you a middle of the night trip in the cold.
6. DO NOT DRY "WET" CLOTHES IN BAG: Moisture will travel from wet clothes to sleeping bag. If your clothes are wet and you must wear them then next day you must protect them from freezing. Put them in a plastic bag and put them under the foot of your sleeping bag.
7. PUT TOMORROW'S CLOTHES UNDER BAG: This heats up clothes for tomorrow's cold morning and also provides more insulation.
8. FLUFF UP YOUR BAG: Always fluff up bag before using to create the thickness important in keeping warm.
9. MOST IMPORTANT, KEEP IT DRY: Keep all your sleeping gear dry and follow these rules, and winter camp should prove to be a rewarding experience.
10. COLD AIR SINKS - Try to place your campsite on slightly higher ground than the rest of your surroundings. Try to choose a protected site if it is snowing or the wind is blowing
SLEEPING GEAR
If you do not have a winter sleeping bag you can use two summer bags, one inside the other. Or, you can use several blankets in addition to your summer bag. Wool blankets are best. The blankets should be folded to fit inside the bag (best) or around it.
Natural fiber sleeping bags (including down) do not maintain their insulation properties when damp. Be sure to keep them dry!
A mummy style bag is warmer than a rectangular, as there is less space for your body to heat. Also, most mummy bags have a hood to help protect your head.
If you only have a rectangular sleeping bag, bring an extra blanket to pack around your shoulders in the opening to keep air from getting in.
Scouting literature shows how to make foam rubber sleeping systems.
Putting your head under the covers will increase the humidity in the bag that will reduce the insulation properties of the bag.
Air out your sleeping bag and tent, when weather permits. Perspiration and breath condense in the tent at night and the water will reduce insulating properties of your bag.
Hang your sleeping bag up or just lay it out, between trips, so the filling will not compress and lose its insulating properties.
Whatever you sleep in, you need to be insulated from the ground or snow. A good rule of thumb is that you want 2 to 3 times the insulation below you as you have over you. A closed cell foam pad (usually blue, about $6) is essential to get you away from the cold snow and ground. Open cell foam (the familiar old foam rubber) also makes good insulation, but absorbs moisture.
Use a ground cloth to keep ground moisture from your bag. Your body will warm up snow and frozen ground to a point were moisture can become a serious problem. A plastic sheet or tarp works best.
Don't use an air mattress or cot during the winter. Cold air will be above and below you if you do.
Respect for nature and BSA's low impact camping policy discourages using tree boughs for bedding.
SLEEPING ATTIRE
You can use pajamas, long underwear, sweats, etc. to sleep warm depending on the quality of your bag. Don't forget socks. NEVER WEAR ANYTHING TO BED YOU HAVE WORN DURING THE DAY. This is so you go to bed as dry as possible (no perspiration in your clothes) and start the next day dry also.
Wear a stocking cap to bed in order to reduce heat loss or wear a loose fitting hooded pull over type sweatshirt to sleep in. Here again, it should be one you have not used during the day.
Before you get out of bed bring the clothes you plan to wear inside your bag and warm them up some before dressing.
OTHER ITEMS
Exercise before bedding down to increase body heat. This will help to warm your bag quicker. Be careful not to start perspiring.
It is never fun to wake up in the night having to go to the bathroom, especially when it is 10 below. As much as possible take care of this before you go to bed. If you do have to urinate in the night, it is possible to do this without having to get out of your sleeping bag. If you are VERY CAREFUL you can use a plastic bottle with a tight lid, a zip lock plastic bag or even a commercial urinal. Remember to empty the bottle away from the camp in the morning.
It is a good idea to keep warm drinks available in a water-tight bottle or canteen. If you are sure the bottle is water-tight, fill it with hot water (not boiling) and keep it in your sleeping bag to keep it and you warm. If you wake up in the night, it may be because you started to chill do to lack of energy in your body or dehydration. A warm drink will taste mighty good.
