riding Electric heated vest review
I'd been considering
adding heated arm coverage to my
motorcycle electric heated vest for quite
some time. That and heated neck coverage
too. Though my regular Widder electric
vest was plenty warm, my thinking was
that by heating more surface area, I
could use a lower setting. And to my mind
a low simmer is more comfortable for long
rides than a setting at roast (for
more info).
However, I wasn't sure I
wanted a full sleeve model. While there's
nothing wrong with full sleeve heated
garments (they're convenient), it seemed
to me that they might also decrease
versatility.
Over time I've developed a
method of dressing when dealing with the
elements (whether skiing, hiking, riding
etc). To avoid the Michelin man feeling,
every piece of garment has to give
maximum return for its bulk. That's why
the Widder arm chap system seemed like
such a clever and elegant solution. When
I dont need heated arms, I unsnap
the chaps and roll them up. Simple.
I can turn the electric
heated vest on during a chilly morning
ride and have the arm chaps provide
welcome warmth. As the day heats up, I
turn the vest off. The arm chaps don't
add any bulk around the shoulder/arm
junction. Nor do they prevent cooling
ventilation with my jacket vents open the
way attached sleeves would. In fact, if
the temperature is not too warm, they can
stay on all day and not cause discomfort.
In addition, the System2
Lectric heated vest has a heated collar.
I find it very effective and comfortable.
Of course this is a personal preference.
Some like a vest with a collar, others
prefer without. I like with.
The outer shell is
constructed of a light windproof
Cordura-type material and seems quite
effective, though I have to wonder if a
wind flap over or under the zipper
wouldn't further increase sealing against
cold wind. For warmth retention there is
a light layer of Thinsulate.
What I found:
Vest: The
Widder heated vest is very effective. It
provides good heat and is comfortable to
wear. It is rated betweem 33 and 35 watts
for most sizes. This makes is
particularly suited to motorcycles with
lower output alternators.
However, this lower watt
rating also means a lower total heat
output. To get a fix on this, I set up a
standardized test and took some
temperature readings. I was not concerned
about temperatures achieved by the
heating elements. Rather, I was
interested in seeing how much heat was
radiated by the liner to warm up the
internal air space.
This involved suspending
the Widder heated vest on a hanger and
sealing off the sleeve and neck openings.
I then suspended a heat probe at about
sternum level and at about the same
distance from the front and back of the
liner. I was looking to measure how warm
the internal air space would become from
the radiated heat. No contact with
elements allowed.
I observed the following:
At full power and 20 minutes from
cooldown, I measured 36C (96.8F). It's
not that the individual elements don't
reach a high enough temperature. They do.
It's just that, for the 33 watt draw,
there are relatively fewer elements, not
enough to raise the inner air temperature
higher. This means that the Widder vest
needs to be worn very snuggly and close
to the skin for best results. It warms
best by contact, and puts out relatively
low amounts of radiated heat. This is not
a fault but a result of the low watt
draw.
Heated Chaps: The
heated chaps draw a total of 20 watts, 10
watts per arm. As such, they put out
relatively less heat than the vest in
terms of surface area. Again, this is not
a surprise but is a function of the low
watt draw. Keeping this in mind, as they
warm stricly by contact, best results are
obtained when wearing the arm chaps very
close to the skin ie over a t-neck
sleeve.
Overall:
The Widder System2 heated
vest and ArmChap combo provides good
versatility. I think of it in terms of
technical clothing. Wearing it close to
the skin results in maximizing heat
transfer.
