2. Choosing the right stuff
• What is wrong with this
picture??
• The right choice makes all
the difference
• Sometimes the choice can
be very difficult
3. How do I know?
• Learn about what clothes
work in certain weather
and which ones do not
• There is no right or wrong
• Personal comfort is
different for everyone
4. Heat loss and your body
• We loose heat in 4
different ways:
• Convection (wind)
• Evaporation (sweat)
• Conduction (contact)
• Radiation (skin)
5. Prevention of heat loss
• Severe heat loss can lead
to hypothermia
• Clothing choices can
affect heat loss
dramatically
• How we use those clothes
can have an affect as well
6. The Layering System
Some questions we will answer:
• What is a layering system?
• What should it do?
• Why should we use it?
• What are examples of different layers?
7. What is the layering system?
• Using different materiel to
protect our body
• Easily changed to adapt in
various situations
• Ideally made up of quick
drying, breathable parts
8. What should the layering system do?
• Keep the wind and water
out
• Keep the heat near our
body
• Dry quickly
9. Why use the layering system?
• Very versatile in all conditions
• Keeps you warm and dry
• Keeps you safe and happy
10. What are examples of different layers?
• The Base Layer
• Known commonly as
“Long John’s”
• Moves water away from the
skin
• Hydrophobic
• Thin and light for quick
drying when wet
• Made of Polyester
11. The layers continued…
• The Mid-Layer
• Known as a “Fleece” coat
• Much thicker than the base
layer
• Tight fitting to avoid heat
loss through convection
• Creates a layer of warm air
around your body
• Made of Polyester
12. The layers continued…
• The outer layer or
“Shell”
• Wind proof or Water Proof
• Thin protective shell
• Usually has a hood
• Ideally breathable
• Made of Polyester
13. Other layers…
• For extreme conditions a
very warm layer might be
needed
• A down “puffy” jacket or
very thick fleece sweater
will work fine
• For cool but dry
conditions a light shell
will do the trick
14. Check your Head
• 2 of the Beastie Boys have
got it right
• Why?
• The head is very exposed
and a lot of body heat can
be lost from there
• The back of the neck is
another area to cover in
extreme temperatures
15. Hands and feet
• These are the extremities
• Feel the cold here first
• Why?
• How should we protect
them?
16. Hands
• Mittens are warmer than
gloves
• Why?
• They make doing things
impossible however
• Gloves have fingers and
make things easier to use
17. Feet
• Feet need to stay DRY or they get
COLD
• Waterproof boots help but our feet
tend to sweat a lot inside of them
• Changing your socks is very
important to keeping feet warm
• Feet loose most of their heat
through…
• Conduction!!!!!
18. What you need…
