COLD WEATHER SLEEPING SYSTEM
Sleeping conditions along with keeping warm and having the proper nutrition is key to
making winter camping enjoyable.


· The body cools down during sleep. The blood (heat) is drawn from the extremities and brought to the center  
(
core) of the body
· The ground is always colder than the body. Proper insulation must be provided to prevent heat loss by
conduction
·
C-O-L-D, is the key to staying warm


C   Your bedding should have washable liner so that it stays Clean

O   To keep from Overheating, bedding must be vent able

L   Bedding should be lightweight and large enough to accommodate you. Use a Layered system

D   Keep gear as Dry as possible, push all the warm, moist air out in the morning and then air and dry
the bag in the morning sun



Ground / Floor Insulation

· Good insulation should cover the entire floor of the sleeping area
· Adequate protection under a sleeping bag requires a minimum of 3/8 to ½ inch thickness of a good firm
insulation. A 1" thick open-cell foam pad is not adequate; it gives much less than half at the pressure points
(hips, shoulders, ect...)
· The open-cell pad can be used on top of another pad


Sleeping Bags

· Sleeping bags for winter camping should be rated to temperatures below what you expect to experience
during the trip if you want to be comfortable.
· Using two lighter bags in combination is a popular and efficient choice
· Construction and fabric
(fills) vary and should be considered (in terms of price, weight, volume) carefully before
purchase and/or use.
(see discussion on Insulating Materials)


Washable, Insulating Liner

· Good investment if chosen properly it can double as an ultra-lightweight summer bag
· Wash often, keeping sleeping gear clean and dry for optimal insulating performance


Sleepwear

· Feet are critical, dry feet use foot powder with aluminum chlorohydrate, wear loose insulator (socks can not be
tight)
· Use a  "sleeping suit", a clean, dry set of thermal underwear (if temperatures warrant, a second, looser layer
can be added)
· Stocking cap, wristlets, scarf can be used at night as long as they are dry and clean
