Searches can occur in good weather, but we are often called out
because poor weather conditions threaten the missing person.
Temperature, precipitation and wind can threaten not only their lives,
but also yours, so be sure you are prepared for the conditions at the
search, whatever they may be.
Principles:
Wicking: Having moisture next to your skin can
cause blisters, and in cold weather make you cold and
miserable. Materials like polypropelene conduct moisture away
from your skin, as a wick conducts wax to the flame of a
candle, keeping you dry. Cotton retains moisture like a
sponge, (that's why it is used to make towels) making it a
poor choice for socks or clothing in wet or sweaty
conditions.
Warm When Wet: Most clothing insulates by retaining
pockets of air. The air does the work, while the clothing acts
to keep the pockets intact. Down jackets, comforters, and
thick quilts work this way. However, when these materials get
wet, they cannot keep you warm.
Warm when wet materials, like polyester fleece and wool, can
keep you warm even when soaking wet. Sopping wet wool has been
found to be warmer than even dry cotton.
Layering: Multiple thin layers will keep you warmer
than a single thick layer, as heat has to pass through each
layer to leave your body. By dressing in layers, you can also
adjust your clothing to keep comfortable. Conditions can
quickly change during a search. For instance, members of PVRG
went on a hike along the Appalachian Trail a few years ago. It
started out very cold, with snow on the ground but as time
passed, the sun came out and the temperature rose to 60
degrees. If you wear a single sweatshirt, you can only roll up
your sleeves or remove the shirt, which will probably leave
you either sweating or freezing. If you wear multiple layers,
you can take off or add a layer as needed. It is best to
arrange layers so that you only have to add or remove to the
outermost layer, and aren't juggling shirts on the trail.
Also, layering insures that you always have enough clothing
around. In an emergency, a spare shirt could be used as a
sling, cut into strips and used as cord, burned, as a flag,
etc.
Dressing Cold: In cold weather it's not good to
break a sweat. When you stop hiking, the sweat will cool you
down rapidly, and you'll be wet to boot. In some cases, it's a
good idea to "dress cold", or wear just enough clothing to
stay warm when you're burning calories by being active on the
search. When you stop to take a break, you will cool off, but
not as much as you would if you were soaked with sweat. Extra
clothing can go in your pack, or be left with the rest of your
stuff at base.
Durablity and Utility: It's a good idea to get
clothing that can stand up to thorns, mud, climbing over
rocks, etc. Also good to have pockets, zippers, hoods,
anything to maximize the usefulness of the clothing.
Minimum Clothing Standards:
Wind/Rain Protection
Layers to keep you dry and comfortable for the
conditions
Good, broken-in boots or shoes
Rain Gear
Plastic Poncho: Good for heavy rains and warm
summer storms
Pros: Cheap, compact, easy to find or make from
garbage bags, one size fits all, totally waterproof,
disposable, covers backpack as well, and can be used
for shelter
Cons: Not durable, leads to sweat condensation,
not very good in windy or cold conditions, sides are
open to elements
Nylon poncho or jacket: Good for light rains, from
spring to fall.
Pros: More breathable than plastic poncho, more
durable. Jacket offers more coverage than poncho and
is better in the wind, some have pockets or zippers.
Poncho can cover backpack and be used as shelter.
Cons: Not totally wind or waterproof, poncho has
open sides
Rain Coat
Pros: good in wind
Cons: Can't cover backpack, be used as shelter,
not as compact as other options
Waterproofed Winter Coat
Some winter coats are made of Gore-tex or similar
materials, and are waterproof as well as warm. Many
coats can be made waterproof using special chemicals
in the washing machine, which allows the coat to still
breathe. These are good for winter operations.
Insulation and waterproofing in one layer.
Cons: can't cover backpack or be used as shelter,
too warm in any other season, not very compact.
Pants
Jeans: the worst of all pants in the rain, jeans
have a tight weave and will keep you wet and cold for
hours.
Cotton pants: hold water, keep you wet, lose
insulation power, a bad idea if there's even the chance of
rain. Cotton/synthetic blends slightly better
BDU's: recommended by the ASRC and other groups,
surplus Battle Dress Uniform pants are made of special
synthetics, and will keep you warm when wet. Excellent choice
year round when combined with other layers, like long
underwear.
Rain pants: good choice when combined with other
layers.
Layers To Keep You Comfortable
Not cotton, if possible. This includes denim and
T-shirts.
Blue BDUs are recommended, as they don't rip, are durable,
and stay warm when wet. They have buttoning pockets, a button
fly, drawstrings at the ankles, and will work without a belt.
Excellent pants all around.
Try to use wicking materials close to your skin, with
layers of warm when wet clothing on top.
A good winter jacket/parka is a good idea in winter, as
are long underwear
Shorts aren't a very good idea, even in summer. Long pants
will keep thorns, nettles, and ticks from making you
miserable.
Sturdy Shoes or Boots
Something you can walk over rocks, trails, through wet fields, snow
without hurting your ankles or soaking your feet. Should be sturdy and
preferably water resistant or waterproof.
Sneakers/Tennis Shoes: can work with good socks and
changes of them, ie wool or polypro socks.
Trail Shoes: even better.
Hiking Boots: best choice, ankle protection, some
are waterproof or resistant.
Combat Boots: good choice if you're used to them,
ankle protect
Suggested other things:
Gloves: to keep your hands warm, but leather gloves
are also handy in that they protect you from thorns, abrasions
from ropes, and in handling the litter
An extra pair of socks: It's always nice to have a
nice clean dry pair of socks to change into.
Hat: Keep your head dry and comfortable, and keep
the sun out of your eyes.
Broad Brimmed: sun, rain protection, not
very good insulation.
Wool/watch cap: good insulation, not good
sun or rain.
Baseball Cap: good sun, ok rain not good
insulation, good with a hooded coat.
Sunglasses: good for reducing glare, yellow filters
help pick out details in woods, but may make colors more
difficult to interpret
Sunscreen: to protect your skin, even in
winter
Bug repellent: to keep from getting bitten
Lip Balm: Protect your lips
Gaiters: keeps leaves and moisture from getting
into the tops of your boots
