Review Date: February 12 2006
6' 0" (183 cm)
270 lbs (122 kg)
League City, Texas (U.S.A.)
My backpacking started in the scouts, and has been an important part
of my life since my introduction to it in 1980. Living in Texas with
an uncooperative spouse made going places to go backpacking difficult.
Changes in that status have gotten me back on the trails. I consider
myself a mid weight backpacker, but some definitions fluctuate. My
base pack weight averages 19 lbs (8.62 kg). My camping experience
includes camping from the car, canoe camping, and backpacking.
Year of Manufacture. 2005
Manufacturer URL. www.coleman.com
Weight as claimed by manufacturer. 2.7 oz (77 g).
Weight as tested. 2.4 oz (68 g) including stuff sack.
Stove height (approx) 3.25 in (8.25 cm).
Stove width folded (approx) 3 in (7.6 cm).
Pot support span 4 in (10.1 cm).
Stove height assembled to recommended fuel canister. 6.5 in (16.5
The stove is a simple screw down burner design, atop folding legs,
atop a small valve / venturi assembly. The fuel control knob is a
simple wire loop controlling a knob. The whole thing is made from what
appears to be aluminum, stainless steel, brass, and plastic. Included
is a small, nylon stuff sack with drawstring and cord lock.
MSRP: $39.99 US

above mean sea level. Easy trails posing little to no challenge beyond
muddy conditions, and alligators, daytime highs in the upper 90s (50
C), hot and humid, stove needed very little due to lack of desire for

Review of the Coleman Exponent F1 Ultralight
After years of swearing I would never use another stove in favor
of my old MSR Whisperlite, my aging back won out the argument of
whether buy lighter gear or not. While the Whisperlite is far from a
heavy stove, and it has some notable advantages over the canister
stoves, I chose a canister stove in order to lighten my load, and
improve the ability to simmer. I read all the reviews I could find,
borrowed as many stoves as I could, and annoyed the sales staff at all
the backpacking shops to get information on the various models of
stoves. And I boiled it down to a Butane / Propane mix burning
canister stove. But the question was which one?
Well since I was going for light weight, the lightest advertised
weight I could find was the Coleman Exponent F1 Ultralight. That is at
least for a stove that had a controllable, adjustable flame (soda can
stoves are lighter). The stove's advertised 2.7 oz is feather light.
There were a fair number of worthy competitors in this market niche,
all offering light weight, low price, and good performance, however
the Coleman won out on the factor of weight alone. The Exponent F1
Ultralight was simply the lightest model I could find.
I was pleasantly surprised at the fact that the actual delivered
product weighed less than advertised. In backpacking gear this is
rarely the case.
In my efforts stove reviewing efforts, I "test fitted" pots to
various stoves, and found no issues with the Coleman not supporting
pots, or being wobbly with most pots. However there are some pot
designs that have a recessed bottom that don't fit this stove
particularly well. Test fitting the pot a user may either have, or
will buy, to the stove is important for insuring pot / stove stability.
Setting the stove up for its initial trial run prior to taking it
out on the trail at home, I set it up on the back deck, and boiled a
quart (.95 l) of water in my old American Camper backpackers Stainless
1L cook pot. Time to boil, while not measured did seem quite rapid.
Setting the stove up is somewhat awkward the first time it is
done. The burner head has to be backed off 1 to 2 turns before the pot
supports can be rotated into position. Once the pot supports are in
place, the burner head is then tightened down to hold the pot supports
in place. With the stove assembled, but not on the fuel cylinder, both
the fuel cylinder, and stove connection should be inspected for debris
or damage to insure safety. Screw the stove to the cylinder snugly,
set the assembly down, strike a match, and turn the gas on, and the
stove comes to life. One item this stove does lack, that impacts its
usability is a piezo igniter. This can be a positive or a negative.
Matches, or a lighter must be carried to ignite the gas. And there is
no added weight, or added complexity or point of failure of the piezo
The setup was fast and simple. As was the boil time. I honestly
think the time to boil a liter of water was identical to the white gas
stove. There was no pre-heating, pumping, or complicated assembly
involved. During testing, some cold weather startup issues were noted
as the temperatures dropped below the freezing point, and the winds
picked up. This behavior was easily overcome by simply turning up the
control valve a little further than usual.
Cold temperatures did not seem to impact the way the stove worked, but
the breeze / wind definitely had an impact on this stove, and made it
painfully obvious that it had no wind screen.
What I liked.
1. Light weight. This is the lightest canister stove I have come
2. Low Cost.
3. Ease of use.
4. Ability to go from extremely low simmer to flamethrower.
5. Quality of construction. This thing is built really well for
something so tiny and light.
6. Pot stability with wider pots than competing stoves due to a
wider support footprint.
7. Exceptionally easy to set up and get working in mild to hot
What I disliked.
1. The finish quickly oxidized after the first use. By the time I
got back from Oregon, there was a coat of dull aluminum rust on what
had been polished aluminum. Sealing the surface of the product would
be a good quality control improvement. However this is a functional
object, not an art object No biggie.
2. I alluded to this earlier, the pot rests are just the wrong
size for certain pot designs. It is important to match the cook pot to
the stove pot supports.
3. Less than obvious setup procedure. Once the user sets it up,
it is obvious, but the instruction sheet leaves a good deal to be desired.
4. Lack of windscreen. I am not sure how they could make a
windscreen for this without taking a chance at overheating and blowing
up a cylinder, but I bet it could be done. And without adding much weight.
The stove worked exceptionally well in all conditions except sub
freezing and windy, and even at that a bit of fussing made it roar to
life. Fuel cylinders are not readily available in the Houston Texas
area, and have only been seen by me, or reported to me as being
available at Oshman's, REI, and several area Wal-Marts. I have never
seen them at Gander Mountain, but have been told the canisters are
available there. I have had it reported to me that fuel is much more
common outside of TX. I did see the fuel cylinders just about
everywhere I looked when I was in Oregon, campground stores, gas
stations, discount stores etc The poor cold weather ignition
performance of this stove I do not believe was indicative of a flaw
with this stove, but rather canister stoves in general. I will not be
parting ways with my trusty old Whisperlite for trips up north during
cooler times of year, however I look forward to years of enjoyment of
this stove at lower elevations and warmer temps. This is the stove I
wish I had owned in Arizona!

- Hi Dave,
You are in good shape on the HTML, except that the Coleman link needs
to be made clickable (to the URL indicated in your text, please, not
the redirect to home.asp that the Coleman site defaults to--we always
link to the main page, as redirects can change). Once you have done
that, you may upload to
Don't forget to mark the "Owner Review" radio button.
Pleasant working with you. I look forward to seeing your next OR.
- Dave--not a big deal, but propane and butane are still capitalized in
the HTML. Truly, these are don't need capitalizing. It doesn't
interfere with your meaning, and if you are more comfortable with them
that way, that's ultimately OK by me. However, it is, strictly
speaking, incorrect. If they were trade names, that would be a
different story, e.g. Velcro, Flagyl (to take two at random) but
chemical names are no different from any other noun in taking lower
case when in the body of a sentence.
The changes you asked for have been included in the HTML, and the new
file has been uploaded. Photos are pending a trip this upcoming
weekend. (I want to photograph it in use).

- Great! Upload as indicated when ready. Test your layout with the
images in the test folder first. Images should not exceed (at the
outside) 600 px; 450 px is better, IMHO.
