I have over 30 years backpacking experience, starting with Scouting
as a youth. I am currently the High Adventure Leader for a Scout
Troop. I try to get out once or twice a month, plus at least one week-
long trek each year. My trips are of two types. First, I am hiking
the Pacific Crest Trail in sections, and generally use a lightweight
approach on these typically solo trips. Other trips involving family
involve more traditional backpacking equipment. Terrain varies from
sea level to 14,000 feet (4,300 m), desert to mountain, and trail to
cross country, occasionally including snow travel.

Sierra Designs claims that the hood will "allow you to configure it
for your preferred sleeping position" and includes belly, side, and
back sleepers. If this was a multiple choice test I would choose "D" -
all of the above, although I prefer to call my sleeping
position "occupy as much space as possible."

THIS IS THE FIRST OF THREE REPORTS OF THE SIERRA DESIGNS VAN WINKLE
SLEEPING BAG and is based solely on inspection at home. Future
reports will describe my experiences with the sleeping bag over two
and then six months.

PRODUCT DESCRIPTION:

The Van Winkle is manufactured by Sierra Designs. The manufacturer's
website at http://www.sierradesigns.com has detailed information on
the unique features of this bag. The Manufacturer's Suggested Retail
Price is $229.95.

The sleeping bag arrived by UPS Ground in a corrugated box in fine
condition. I cut the box open very carefully and was glad I did, as
the sleeping bag, in its storage bag, completely filled the large
box. Cutting the box open with a large knife could have been
disastrous.

Included in the box were:

* Sleeping bag, which I weighed at 4 pounds (1.81 kg) (PHOTO)
* Nylon stuff sack, blue, 18 inches (46 cm) long and 8 inches (20 cm)
in diameter (both measured and per manufacturer), 2 oz (57 g)
* Cotton storage bag, bright orange, approximately 30 inches (76 cm)
long and 13 inches (33 cm) in diameter, 4.5 oz (128 g)
* An attached tri-fold card describing the features of the sleeping
bag and how to adjust the NightCap Hood (TM) for sleeping on one's
side, belly, or back.

The claimed weight of the sleeping bag is 3 pounds 3 ounces (1.45 kg)
according to the hang tag and 3 pounds 6 ounces (1.53 kg) according
to Sierra Designs' website, but mine weighed 4 pounds (1.81 kg),
which is 13 ounces (369 g) or 25% more than that listed on the hang
tag. I was very disappointed, but not surprised, to find that the bag
weighed so much more than advertised. I do not understand how the
manufacturer weighed the bag. Slight variations in fabric weights do
occur between lots, but this seems excessive. Maybe they only weighed
the down fill and shell fabric and left out the weight of the zippers
and webbing!

The sleeping bag is made of smooth 50D polyester, rust orange color
outside and black inside. There is a faint pattern to the fabric
which I presume must be what the manufacturer calls "octa-rip"
or "fancy ripstop" as the typical heavier ripstop threads are not
present. The outer fabric has a durable water repellent (DWR) finish.
The inner fabric is claimed to be moisture wicking. The fabric tag
states the finished size is 94 x 31 inches (239 x 79 cm), which is
what I measured the fabric of the shell to be when laid perfectly
flat. The girth of the bag is also listed different on the hang tag
and website, as follows:

Per hang tag Per website My
Girth Normal Flexed Normal Flexed Measurement
Shoulder 62" 68" 66" 72" 66"
(157 cm) (173 cm)(168 cm)(183 cm)(168 cm) (measured inside
sleeping bag at longest seam)
Middle 56" 62" 56" 62" 56"
(142 cm) (157 cm)(142 cm)(157 cm)(142 cm)
Ankle 41" 43" 42" 44" 41"
(104 cm) (109 cm)(107 cm)(112 cm)(104 cm)(measured inside
sleeping bag one seam up from the bottom end of the bag)

The Van Winkle is filled with 28 ounces (794 g) of 600 Fill Goose
Down, according to Sierra Designs' website, although the weight could
not be measured. The fabric content tag indicated that the contents
were "Goose Down Minimum Down 75%. This was on a sticker which
covered printing on the tag stating "Goose Down Minimum 80% Goose
Down." The fabric care tag simply says "Goose Down." There is
embroidery on the bag reading "Van Winkle 600" which does suggest the
down is 600 fill. Because none of the tags sewn on the bag state the
down quality, I do not know if the fabric content tag was originally
printed incorrectly and corrected with the sticker, or if the quality
of down used in the bag changed after the tags were printed. A higher
percentage of down versus feathers results in higher loft for the
same weight, and, therefore, less fill is needed for the same loft.

The seams all appear to be well made and free of stray threads. The
fabric appears to be very down proof, having only found two stray
feathers poking out in a week of pushing and poking at the bag. The
outside fabric is water repellant, and a couple tablespoons of water
dropped on the bag just sat there in a pool until wiped up (PHOTO).
The inside fabric is "quick drying" and "highly wicking." Water drops
on the inside spread across the fabric quickly.

The Van Winkle is one of Sierra Designs' Flex (TM) sleeping bags.
According to Sierra Designs, "The Flex construction has flexible,
expandable baffles that increase the girth where you need it, without
creating empty spaces that lead to cold spots." The outside baffle
seams look like they are elastic (PHOTO), and stretch. The inside
seams do not stretch.

Another unique feature of this bag is the NightCap Hood (TM). The
hood has two drawstrings. The first, a round cord, is in the usual
location to cinch the hood closed around the face. The second is
located just short of the top of the hood. If this flat lace is left
loose, the hood has enough room up top for me to sleep with my arms
extended over my head while still inside the warmth of the bag, or to
sleep with my arms under my head like a pillow. With the NightCap
Hood and Flex Construction, it is possible to sleep in any position
with all arms inside the bag, and to turn inside the bag without the
usual restriction of a mummy bag. (PHOTOS)

The main zipper is a 66 inch (168 cm) YKK zipper. This zipper can
also be opened near the foot of the bag for ventilation. The long
bags are right-zippered. There is a second zipper on the left side
that is just 7.5 inches (19 cm) long that will open the top of the
bag a few inches for extra ventilation. Both zippers are backed by
insulated draft tubes to keep out the cold. The draft tubes have a
heavier fabric facing the zipper to prevent snagging the zipper in
the fabric.

Attached to the bottom of the sleeping bag are two Pad Locks (TM).
These are thin web straps attached at either side of the shoulder and
midsection of the bag. They are light and easy to use, adjusting with
a ladder lock buckle. The lower Pad Lock is sewn with a spacing of
23.5 inches (60 cm). The spacing between the Pad Lock at the
shoulders is 24 inches (61 cm). It is possible to put a somewhat
wider pad in, but this will cause the sleeping bag to spread wider
and lose vertical space inside as well as flatting the loft. Narrower
pads will fit well, of course, but tightening the Pad Locks too
securely around them will cause the sides of the bag to pull
together, narrowing the room inside. (PHOTOS) Leaving them a bit
loose still keeps the pad under the bag.

The stuff sack is made of fabric a bit heavier than the sleeping
bag's shell. The seams are all finished and there is a pull loop at
the bottom to hold them sack while removing the sleeping bag. The
draw string is sturdy and has a toggle closure, but the round flap to
close the sack has unfinished edges that show a tendency to unravel
and is, in my opinion, just a bit too small. The stuff sack itself is
properly sized for the sleeping bag, requiring just a bit of effort
to stuff the last bit of sleeping bag inside.

INITIAL IMPRESSION:

So far, in the comfort of my living room, the Van Winkle is even more
comfortable than advertised. The Flex Construction allows more
freedom in the bag without compromising warmth. The NightCap Hood is
the most roomiest hood I've seen on a mummy bag, and I appreciate the
room to stretch my arms over my head. My one big disappointment is
that the weight is significantly more than advertised. I suspect this
will limit my use of the bag during warmer months.

NEXT: The Van Winkle will be used on all my trips during the next
several months. These will be primarily in the deserts of Southern
California where the nighttime temperatures can dip to freezing.
Subsequent trips will include a snow camp at 7,000 feet (2,100 m) in
February. I expect temperatures around 15 degrees F (-9 C) and
possible rain and snow. During this test I will look at how well the
Flex Construction and NightCap Hood accommodate my varied sleeping
positions, focusing on comfort and warmth.

Men's Long Sleeping Bag

Initial Report

Personal Stats:

Name: Clifford R. Haynes
Age: 55
Height: 5' 11" (180 cm)
Weight: 300 pounds (136 Kg)
Girth at Shoulders: 70" (178 cm)
Girth at Middle: 52" (132 cm)
Email: chaynes-F7/***@public.gmane.org
Location: Western Maine

Backpacking Background:
I am from and live in Maine. I have been hiking, backpacking, and canoe
camping for over 45 years. I average 2 to 3 days a week in the woods year
round.

I can't really say that I have a backpacking style. I take what I need or
want, depending upon what I plan to do on the outing. Even before my knees
became a problem, I could never see being in a big rush. It is my opinion
that camping is part of backpacking, and should be enjoyed at least as much
as the hiking. In areas where there is a lot of hiker traffic, I tend to
pack heavier in order to minimize impact. I just like being out in the
woods, and exploring.

When I applied for this test, I applied for the men's long Van Winkle
instead of the regular. The regular was the proper bag for my height, but I
wanted the addition girth of the long Van Winkle. I also normally bag and
keep my boots inside the foot of my sleeping bag during cold weather, so
needed the extra length for my boots.

Initial Report:

My Sierra Designs Van Winkle sleeping bag arrived on 9/24/2004 in a large
cardboard box. Upon opening the box, I found the Van Winkle packed in it's
orange cotton storage sack. I removed the Sierra Designs Van Winkle from the
storage sack for inspection. There was a hang tag attached to the top zipper
pull. The hang tag highlights the features of Sierra Designs Flex sleeping
bag series. The Van Winkle has a burnt orange front and dark blue back and
hood. I carefully inspected the seams they were straight and could find no
loose threads or snags. I ran the zippers up and down several time, they
operated smoothly and I didn't experience any snags. The Van Winkle appears
to be well made of quality materials.

The first thing to catch my attention was the Nightcap Hood and zipper
arrangement. The hood appears to be huge. The Nightcap hood is designed to
allow the user to sleep comfortably is various positions (on the back, side,
or belly). The hood has two pucker strings. A round lace Face Adjustment
which can be cinched up to reduce heat loss (similar to that found on most
hooded mummy bags), and the flat-lace Crown adjustment which puckers the
crown of the hood, reducing its volume (when the flat-lace pulled up tight
the hood fits similar to a normal mummy bag hood). According to the Sierra
Designs web site, the Nightcap Hood pucker laces are color coded, the round
lace Face Adjustment being gray and the flat-lace Crown adjustment being
black, both laces are gray on my Van Winkle.

The Van Winkle has two zippers. The main zipper is a #8YKK 2 way separating
zipper, approximately 66" (167 cm) long, located on the left side and turns
in to the throat of the Van Winkle. There is a second non-separating zipper,
approximately 8" (20 cm) long, running diagonally from the throat to the
right side of the Van Winkle. Both of the zippers have draft tubes witch are
trimmed with packcloth (for snag free zipping).

The exterior shell of the Van Winkle has small elastic gathered puckers
running around the bag between the baffles (Flex Construction). This allows
the Van Winkle girth to expand and contract. The body of the Van Winkle can
expand approximately 6" (15 cm) throughout the leg and body and 2" (5 cm) at
the ankles. There are two black 0.5" (1.3 cm) wide nylon straps (Pad Locks)
attached to the back of the Van Winkle, one at the shoulders, the other at
the hips. The Pad Locks are adjusted to the desired length (in order to
anchoring the Van Winkle to the sleeping matt) with plastic buckles. The
maximum length of the Pad Lock straps is 32" (81 cm).

First Impressions:

As I mentioned earlier the hood of the Van Winkle appears to be huge. After
inspecting the bag, I had to try it out. I laid out the Van Winkle on the
living room floor and got in. The Taffeta lining material felt soft and very
comfortable against my skin. Upon zipping the Van Winkle, I was surprised
when the zipper slid closed easily and without snagging. I'm fat and I
generally have a hard time zipping sleeping bags (generally only part way.
The main zipper of the Van Winkle easily zipper right to the top. Frankly
given my girth and the advertised girth of the Van Winkle I expected it to
be much tighter than it is. Even though the Flex Construction is fully
stretched, the Van Winkle doesn't feel like it is squeezing me. The Flex
design seems to relax, rather than stretch, in order to accommodate my
girth. I can actually be comfortable with my arms inside the bag. I unzipped
the short diagonal zipper on the right side of the Van Winkle, rolled on my
side, and slipped my arm into the Nightcap Hood and under my head. With my
head nestled into one the left corner of the Nightcap Hood, I was very
comfortable (and very hot). The Van Winkle was just too warm to continue
playing with indoors, I decided I needed to get out for a quick overnight.

A couple of days later I managed to get out for a local over night outing.
As a campsite, I chose a local hilltop at about 2300' (701 m) elevation. The
hill top is open and usually quiet cool. I used an MSR Hubba Hubba tent fly
as shelter (with the vestibule rolled open) to stay as cool as possible. The
lowest temperature I recorded was 43 F (6 C) at about 3:15 AM. Wearing
shorts and a light cotton tee-shirt I was too hot with the Van Winkle zipped
up. I needed to open the zippers to cool the bag enough to sleep
comfortably. It was cool enough for me to appreciate the Nightcap Hood. I'm
a side sleeper and usually sleep with my arm under my head. I woke a couple
of time during the night with a cold left side due to the open main zipper,
but as soon as I rolled back to my left side I warmed right back up and went
back to sleep. I was very happy with the Van Winkles performance. I found it
very comfortable and even though it was snug, it wasn't as restrictive as my
other sleeping bags.

When I applied for this test, my plan was to use the Van Winkle with the
Sierra Designs Down Stretch Addition, a Flex Construction panel that zips
into a sleeping bag's main zipper and adds 6" to 10 " to the sleeping bags
girth. I have been using a down Stretch Addition for about a year and a
half. Unfortunately I left my original Stretch Addition at out camp in Nova
Scotia for the summer and didn't have it for the beginning of the test.
Since I am very happy with my old Sierra Designs Stretch Addition, I ordered
a new one to use for testing the Van Winkle. It arrived before the weekend,
so I was able to get out for another overnight before writing this report.
For this outing I canoed to a campsite on the river bank at an elevation of
about 400' (120 m), about a mile (1.6 km) below small lake. I used the MSR
Hubba Hubba fly as a shelter again with the vestibule rolled open. The
lowest temperature I recorded was 35 F (1.5 C) at 4:10 AM. I was comfortable
sleeping in shorts and cotton tee-shirt after I got the zippers adjusted for
the temperature. With the Stretch Addition I wasn't awakened during the
night with a cold side. Sometime during the night I did snug up the Nightcap
Hood's Face Adjustment.

I found on the first outing that the Sierra Designs Van Winkle was
compatible with my girth, but the addition of the Stretch Addition improved
my comfort level. I plan to use the Van Winkle with the Stretch Addition
through the majority of the test period (especially in cold weather
conditions). I will be submitting an Owner Review of the Sierra Designs
Stretch Addition to BackpackGearTest.org in the future.

I have not yet tried the Van Winkle's Pad Locks in the field. I'm a bit
concerned that due to my girth, I might rip out the seam where they are
attached to the Van Winkle. They don't appear to have been designed for the
stress that a user of my girth will exert on them.

Test Plan:

I will be using the Sierra Designs Van Winkle as my primary sleeping bag
throughout the test period. My primary interest will be warmth, comfort,
reliability, and durability. Given the expected normal winter temperatures
here in Maine, I expect to test temperature rating of the Van Winkle. I plan
to be out for overnight outings weekly and have several multi day trips
planed for this winter. These outings are planned for Northern Maine and the
Western mountains of Maine. I will be camping using an MSR Hubba Hubba tent
(or just the fly) through most of the test period, but plan to get in some
hammock camping by the end of the test.

I would like to thank Sierra Designs and BackpackGearTest for the
opportunity to participate in this test.
