Park the double wide in your car before you head out for a romantic rendezvous.

Sleep like royalty inside the two-person Big Agnes King Solomon Sleeping Bag. This dual-person 15-degree down sleeping bag features enough room for two happy campers to snuggle up at night and tell bedtime stories with happy endings.

  • Big Agnes sleeping bags leave out bottom insulation both to save weight and because down compressed by your body weight loses virtually all of its insulating value
  • Integrated sleeping pad sleeves keep you from rolling off your pad at night
  • Note: bag requires two 20-inch-wide rectangular sleeping pads to be fully insulated (sleeping pads available separately)
  • Down-proof ripstop nylon shell and lining stand up to abuse and prevent the down insulation from poking through
  • Water-resistant coating protects the down insulation from condensation, frost, and water-bottle spills
  • The 600-fill down keeps the bag lightweight and ultra-warm during chilly nights outside
  • Insotect Flow Construction uses vertically oriented baffles to control distribution of insulation so as to eliminate cold spots
  • Dual zippers make entry and exit a breeze for both people; dual draft collars prevent cold air from sneaking into the bag on either side
  • Integrated pillow pockets let you create makeshift pillows from spare fleece jackets or other soft gear
  • Included 10-by-21-inch stuff sack compresses down to 10-by-10 inches
  • Word to the wise: sleeping pad coupler straps (available separately) help prevent the sleeping pads from inching apart during the night

Great double bag

  • Familiarity: I've used it several times

My wife is onboard with camping now. Not sure what else to say!

Okay, I could say little more. The bag kept us very comfortable in mid-30's temps. I've used it solo in the upper 30's and it worked fine (though obviously not as warm as a single bag).

This bag is rated to 15 degrees which means you should be comfy at 30 degrees. My GF is a warm sleeper and kept the bag extra warm so when we backpacked at 25 degrees, we were plenty warm the whole night. This bag is light enough to backpack with and have lovely features like sleeping pad pockets and pillow pockets that work perfectly. It feels like we are sleeping in a bed (not two sleeping pads pushed together) since the pockets hold them so closely together, there arent any seams.

I love double bags and so will you you

I love double bags and so will you you

What's that saying a happy wife is a happy life. Well you and your partner will not be cold in this bag that i can assure you of. The double sleeping bag from BA is a great product and well worth the price, if you were freezing from your last trip and zipping 2 bags together isn't your bag try this one on for size. I fit perfectly into this bag with room to spare and i am 6'0 tall 200 lbs. Plenty of room for the spouse and even a little bit for fido if need be on those cold nights. High marks for sure here. If you have any questions fire'em over and we'll be happy to answer them for you.

It's Great

  • Familiarity: I've used it once or twice and have initial impressions

I really like this sleeping bag. It's not too heavy and it's pretty roomy for me and my husband. (I'm 5'6 120 and my husband is 5'9 and 155) it's kept us warm so far. only thing is you might want a liner if it get's too much colder. but other than that is been great. We also used the Big Angus insulated air pads.

The Holy of Holies

Spacious, warm, lite (for a double) and my lady enjoys camping more because of it... i.e. I enjoy camping more because of it! Two people with normal temperature tolerance will be comfortable in this bag together at 15 degrees, but any lower than that (in tolerance level or temperature) and you'll want to throw a blanket over the top of you and make sure you have good pads underneath. I'd take this bag into 0 degrees so long as I had good pads and a nice thick blanket to throw over the top... and someone else in the bag with me of course.

Great Double bag.

I've used this bag all over Utah .
Temperatures in the low 20's.
So far it has been nothing but perfect, Plenty of room for my wife and I.
The sleeping pads slip in the back pocket so there is no gap between pads.
It opens up nice for warmer nights.
Couldn't be happier.

I plan on using this bag for sleeping in...

I plan on using this bag for sleeping in the bed of my truck - the dimensions seem a bit large. My bed is about 62in wide and 51in wide at the wheel wells. Is this bag too big for me?

Responded on

check the dimensions. The circumference at the shoulders says 110in. That makes it 55in wide at the widest point. Should nestle nicely in the bed of your pickup. Assuming you have at least a standard full-size short bed (6.5ft long).

King Size Comfort

  • Gender: Male
  • Familiarity: I've used it several times

This bag is nothing short of amazing! It is so warm and comfy. I can't say I've had it out in sub freezing temps but it's been close and most nights I've had to keep the side zippers open to avoid getting sweaty!

The King of Sleeping bags

  • Gender: Female
  • Familiarity: I've used it once or twice and have initial impressions

We took this bag to Algonquin Park in minus sixteen celcius weather. It was awesome. Nice and roomy for my boyfriend (5'-10"), our clothes and I (5'5"). We made a flannel/microfibre liner for the inside which gave it that little extra cozy. Woke up warm and cozy everyday without all the bulky layers of clothing! This bag will be great in Spring and Autumn without doubt. Draft collars work great to keep in all the warm air and cool air out. The Big Agnes King Solomon delivers all around.

What would be the best sleeping mat (set) for this bag? I'll only be using it for 3 season camping, and as for the straps to keep them together which ones are reccomended?

Best Answer Responded on

I have this bag and I use the Big Agnes Dual Air Cores. They're perfect. You won't need any straps to hold them together because this bag has two separate sleeves for the pads.

Love this bag!

This is a great bag - the pillow holders and pad holders work great! My boyfriend and I used this in 28 degree weather and it worked great with just light pajamas on. Plenty of room inside. Our only challenge is that it is too big - we are both small people and it is about 10 inches too long and wide. We even were able to pack it into an unbelievably small stuff sack for back packing. The double zippers work great also.

Would an exped Downmat 7 fit in Big Agnes' double bags? It is 72x20x2.8. I'm worried about the 2.8...

Best Answer Responded on

It should work fine. I haven't found the 2.5" to be a tight fit in the BA bags, plus you usually don't fully inflate the mat anyway.

We LOVED this bag...but temp rating not accurate

Just got back from an early May road trip down the Pacific Coast Highway (northen to central California section). It was May but temps at night were down in the high 30's, low 40's. We used this bag in conjunction with the Big Agnes insulated air core pads. While we absolutely loved the featured of the bag (the neck baffles are brilliant, easily zips, packs down small and has tons of room for the two of us) we got cold. In fat, we had to position our down coats down the sides of the bad near the zippers (both of us, both sides) and we did sleep in hats and insulated underwear, with sweaters on top. I was disappointed in that aspect and had hoped this bag would have been perfect unzipped at this temp...not sure why we were having trouble in the high 30's, low 40's. We did find the bag had PLENTY of room (two women, 5'-4" each). We did not suffer from cold feet however. Great design on the pads sliding in the back, love the color and build quality. Any ideas on getting a higher temp rating out of this bag?

Responded on

I'm considering this bag, but really hate being cold at night. I was wondering if you used additional foam pads between the ground and the pocketed air pads? Is that possibly the difference between the reviewers who were cold, and those who were toasty?

Responded on

No we didn't use extra foam pads but thanks for the suggestion :) I think we will give it a try. I also read that possibly the insulated air core pads have a warm side and a cold side? Because of the cut in hole for the air valve one of the pads gets turned over so you wouldn't be able to keep both insulated air core pads on the same side (if that makes sense) or you could but the air valve would push against the upper pocket area.

Responded on

No down bag is going to perform up to it's rated temp in an environment as damp as NorCal coast... If that's where you're going to be using your sleeping bag you're probably better off with a synthetic bag.

I can't rave enough

Just got home from a month long self contained bike tour in Montana and Canada, and couldn't wait to provide a rating on the King Solomon. This bag is fabulous! Because we carried it on a bike, we might be a bit more flexible about the size than a backpacker, but you can't complain about the weight, basically the weight of two single 15 degree bags, maybe a tad more. One of us carried the sleeping bag and the other the tent. It's not just great to cuddle, it's great because you can move and spread out more, curl your legs up, encroach your legs into the other side territory. We experienced down to 37 degree temp and it was fine, but colder than that and I'd recommend sleeping in long underwear. I'm not sure it would be pleasant at 15 degrees, but suspect it would be fine at 30 or so if you just had long sleeves on or something. My husband stuffed his jacket in the pillow pocket, making it easy to find in the morning. We used thermarest pads which fit perfectly, but other campers told me that Big Agnes pads provide more cushioning, I'm unfamiliar with them. This bag is so well made and clever, the zipper doesn't stick, the top of the bag has scallops to come up around your neck for warmth, you can easily start the night with it unzipped and zip up when it turns colder, it's just the most comfortable sleeping bag I could imagine! We carried it in an ortlieb waterproof bag on the back rack of touring bikes, although it would have fit into a back pannier if we didn't have so much stuff with us.

great bag, but beware

High quality says to use it with rectangular mattress pads but it worked just fine with our Therma Rest Pro LIte Plus'. The temp didn't get below the mid 40's so I can't attest to the low end. However, we were plenty warm in the 40's - enough to have to unzip.
This bag is as good as everybody has stated below, but beware. My wife and I found out real fast that cuddling up is not necessarily a good thing when hoisting 40 lbs. packs all day. It sounds nice and romantic, but in reality it's pretty gross. Sometimes a little distance is a good thing when you haven't showered in a few days.....just our opinion.

Responded on

Umm, if my girlfriend and I didn't get close when we haven't showered in a few days, we'd never see each other.

Responded on

This is a comment on a really old post, but ... you can do a little personal cleanup while camping. Soap works in the woods too! Just use biodegradeble type, away from a water source. Just because you're hiking doesn't mean you have to be gross.

So Luxurious

This bag is ridiculously spacious, and if you have good sleeping pads, you won't miss your bed. It's a tad bulky; I've taken it backpacking before and it works if comfort is your priority for that trip. I usually use a Gregory Z55 and the bag needs to be stored vertically in the pack instead of stuffing it down horizontally into the sleeping bag spot. That being said, it is probably the only two person bag you could viably take backpacking, which is pretty sweet. It has two pillow pockets - hardly a necessity but the GF loves them. REI basecamp pillows or Medium Therm-a-rest compressible ones fit great.

I do not think it lives up to its temperature rating. Both of us started getting chilly in the mid 30's using Therm-a-rest Traillite and Basecamp pads. The Basecamp pad is pretty thick and warm (R-value 5), so I don't think warmth issues were related to inadequate underside insulation and are instead a shortfall of the bag. I have also used 78 inch inflatable mummy pads inside the bag's pad sleeves - they work fine and just stick out the top a little. Fits perfectly in a large Sea to Summit Event compression sack.

Responded on

Given that the amount of down in each side is 18 oz, and comparable 15° 600 fill bags with insulation on top and bottom use 24 oz, this seems like more than enough down to make the rating accurate.

I can't decide if the Big Agnes king solomon...

I can't decide if the Big Agnes king solomon double sleeping bad is worth $90 more than the Big Agnes Cabin creek. Other than losing 5 oz. is there really a big advantage with the king solomon that's worth the extra money?

Best Answer Responded on

If you like down there is... compressibility and comfort are probably the two big bonus' with down.

Responded on

The difference is that the King Solomon uses down insulation while the Cain Creek uses synthetic. This accounts for the weight difference, but down is also a better insulator (when kept dry). When kept in good condition down insulated bags can last a very long time, while synthetic insulation tends to eventually wear out. The trade off for down is that it's more expensive and isn't warm when wet (like synthetics). That means synthetics tend to be better for damp environments.

Responded on

Down vs. Synthetic. No question Down is King! So worth the extra money. This is an item you can have for a longtime. Make the investment.

Great investment for the active/outdoor couple

The best outdoor gear investment I've made in while. Ditto all of the comments below. My girlfriend and I used it on a late winter trip in the Sierra Nevadas. The temperature rating is a bit generous, but as long as you're sharing body heat with someone else you'll stay toasty in sub-freezing temps. Not sure why more manufacturers haven't jumped on the bandwagon and developed more technical 2-person sleeping bags like this one.
