Weather Clothing for Paddling
How We Get
"Cold" & The
Clothing We Should Wear To Prevent It
In
another article we discussed Hypothermia, which is the
lowering of the body’s core temperature. Hypothermia is
the number one cause of deaths (not drowning) in
paddlers. Here's a look at how we get "cold" and the
clothing we should wear to prevent it when we're paddling
in cold weather.
There
are four ways your body looses heat: Conduction, Convection,
Radiation and Evaporation. In all four cases, the warmth of
your body moves out seeking to warm any cold place around
you. When you are out in the elements you want to dress to
prevent these four types of heat loss to keep your core
temperature from dropping too low and causing Hypothermia.
# 1 …
Conduction
is the flow of heat from a warm object in direct contact
with a cold object. If you are sitting on a cold kayak seat,
the heat from your body will flow out of your body to warm
the seat.
Clothing Prevention:
To prevent heat loss through Conduction use an insulating
layer like polar fleece. This will keep the heat coming from
your body from moving into a cold seat or water because the
material is warm and it will slow the transfer of heat.
#2 …
Convection
is the flow of heat from a warm object into a gas or liquid
assisted by circulation of that gas or liquid. An example is
a convection oven where the warm air is circulated
throughout the oven decreasing the cooking time helping food
cook faster.
Clothing Prevention:
Convection heat loss can be accomplished by using a wind and
waterproof material to prevent the wind from cutting through
your clothing.
# 3 … Radiation
is the flow of heat through the space, like the sun shining
on your skin. You will feel the warm from the sun until you
move to a shaded location.
Clothing Prevention:
Radiation heat loss is the hardest to reduce because this
heat must be reflected or absorbed. A space blanket can be
used to reflect the heat back to your body or wearing a
thick sweater can help absorb some of the radiated heat.
# 4 … Evaporation
is the process of changing a liquid into a gas. When we
exercise we perspire and when our skin dries we feel cooler.
Clothing Prevention:
An insulation layer that wicks moisture away from the body
through absorption rather than heat transfer can best
control evaporation. Polypropylene, polyester fleece and, to
some degree, wool are well suited to accomplish this by
absorbing the moisture into the material.
Now we'll take a look
at the specific types of clothing that help to keep
you warm when paddling in cold weather.
A dry suit is a waterproof garment
with tight fitting neck, wrists and ankle gaskets made
of stretchy rubber. The dry suit will keep the wind and
water from soaking you and your insulating layers,
keeping warm air trapped inside. They do not allow for
moisture to escape so wearing a layer of clothing that
will wick the perspiration off your skin is necessary.
By adding an insulation layer to the dry suit and a
wicking layer you will be set for very cold water,
winds, splashing waves, rain and cold air.
A wet suit like the most common
‘Farmer John’ or ‘Jane’ wet suit allows water to seep
into your suit and gradually warm to your body
temperature. Once the water gets warm it will stay there
at a comfortable temperature.
Hats are an important part of
keeping warm in cold weather, as most of the heat is
lost through your head. A polar fleece cap is best.
Hoods and skullcaps made of neoprene are best for very
wet and cold conditions and fit nicely under a helmet.
Look
for gloves made specifically for kayakers, which
come in a wide variety of styles and materials. Pogies
are like mittens for kayakers, but do not have thumbs
and there are holes for the paddle shaft to enter. You
attach them to your paddle shaft, with a flap and a
Velcro closure. A large hole is available to insert your
hand into each pogie. You can then grip your paddle
shaft with your hand inside the pogie. They create a
pocket of protection around your hands and the grip area
of your paddle shaft.
Neoprene boots will keep your feet
warm and protect your feet. They are like a wet suit so
the water will enter your boots but will warm from body
heat. Wearing wicking socks inside your boots can be
more comfortable. Though you will still have wet feet,
they will feel less ‘clammy’.
Hope this information will help you find
the right items to wear while enjoying kayaking in cold
climates There is a video on the
Inflatable Kayak Blog (posted 11-18-2008) that deals
with
dressing for cold water paddling. In this case it’s
in the Arctic, so you know they’re wearing some
effective apparel. |
