I became an enthusiastic backcountry backpacker after taking a 70-day
Rocky Mountain NOLS course in 2007. My husband and I spend about 20-30
nights a year sleeping in a tent. We typically do 3-5 day hikes, but
have completed several larger treks, including the Annapurna Circuit
in Nepal, the Kalalau Trail in Hawaii, the Overland Track in Tasmania,
and the John Muir Trail this August.

PRODUCT DESCRIPTION (by owner)
The Big Agnes King Solomon is a two-person, down-filled, roomy 15-
degree sleeping bag. It has two zippers--one on each side--for handy
in-and-out. It also has draft doggies blocking zipper draft along each
side, as well as individual draft collars. There�s even a draft �flap�
that fills the space between two people�s heads, which you can pack
away handily in a little velcro pocket. It also has toggles to cinch
the bag opening, making for an even toastier sleep. The King Solomon
also has a couple of signature Big Agnes features on the underside: no
insulation, and two slots for holding standard 20� width sleeping
pads. You don�t need Big Agnes brand pads: we use an REI and
Thermarest brand 3/4 length pads. The King Solomon also has built-in
pillow pockets, but we usually just use our clothes stuff sack as a
Since the King Solomon packs into a large mass (and even that, with
some effort), you�ll need at least a 70L backpack (or a wide 60-65L
pack) to stuff it into. My Gregory Deva 60 (circa 2005) can�t hold it
without a serious workout. We use an attack/compression sack and don�t
fully compress it because it takes a long time and effort to get that
last inch of compression.
My husband and I purchased the Big Agnes King Solomon (or �Bagnes,� as
we call her) 2 years ago because we wanted to sleep together when
camping. Frankly, there aren�t many doublewide bags out there, unless
you want to lug 12 lbs around. We�d had great success with Big Agnes
tents, so we decided to give the King Solomon (�KS� from here) a try.
We�ve used the KS in countless environments because we took it with us
on a 7-month backpacking trip in the Eastern Hemisphere. Counting this
and many other backpacking trips, we�ve probably slept 150 nights in
We slept in the KS in temperatures ranging from 0 degrees and 30 mph
wind at 17,000 feet in Nepal in a drafty teahouse on a wood bed to 85
degrees and high humidity in Thailand and Hawaii. Presumably because
there were always two of us sharing the warmth, the KS certainly
seemed more like a 0-degree bag (or warmer!) than a 15. We often
wished we had a 30-degree version of the pack because we were so warm
(obviously it�s overkill for the tropics, but there are no lighter
doublewides, to my knowledge). My husband slept in the KS alone in 20-
degree weather on snow in Colorado for about a week, and he reported
that it was still warm, though he put his pack inside to fill some
Our tent, a Big Agnes Seedhouse SL2, is almost entirely mesh, and the
KS inevitably draws moisture from the walls because its footprint is
the same as the SL2. When this happens, it can be annoying to pack a
slightly wet bag, but the fabric dries quickly in the sun (we toss it
on bushes and have never had a tear). We never noticed loss of warmth
due to condensation issues, nor a significant weight gain.
In over 150 nights of use, I cannot think of one problem with the KS.
Considering we only carry one bag, its a very reasonable weight (not
ultralight, but it�s worth the snuggle ). The sleeping pad slots on
the back are extremely useful and have spoiled us. We�ve tried going
back to the old method of putting the KS on top of our pads, and even
the slightest movement now annoys us. The no insulation on the back
doesn�t seem to impair warmth at all, and makes me wonder why all bags
aren�t made this way. Why waste the down and the weight?
The only difficulty with the KS is compression it. It�s just so large
that it can be difficult to force into even a large stuff sack.
Inevitably air pockets get trapped in the sack during the process, and
sometimes you have to pull out some of the KS and then give it another
try. This is not a tiny, ultralight, mummy sleeping bag. It�s more
like a down comforter hiding in a backpacker-style bag. Though it�s
bulky, it is unquestionably our favorite piece of gear. We strive for
minimalism in other aspects of our packing to make up for the bulk and
slightly higher weight.
If you�re looking for a bag to share with your partner, the Big Agnes
King Solomon is one of the only backpacker friendly bags on the
market. Fortunately, it�s a winner. The thoughtful details like, two-
sided access, draft tubes, draft collars, and sleeping bag slots make
it warm and comfortable all night long. After over 150 nights of use,
the KS shows no signs of wear or warmth, and continues to be my
favorite piece of gear.
No drafts, good access.
Lightweight compared to other doublewides.
Durable (over 150 nights of use with no visible wear).
Handy sleeping pad slots.
Roomy, even with two adults. Nice wide foot box.
Unexpectedly too warm, even in cold temps.
