NEMO - Disco™ Women's Endless Promise® Down Sleeping Bag (15°F/-9°C)

First - are you positive you want to zip together with your partner? I did your same plan \~15 years ago. Got 2 bags and zipped them together. It was cute. At first. Then we soon became cramped / cold. We almost always preferred to be in our own bags vs. zipped together. After the novelty of zipping together wore off - it really wasn't useful. Just saying... don't spend the extra money / effort or limit your options for this feature if you don't really need it. If you still want the zip together bags - you are looking for sleeping bags that have 'left' and 'right' zippers. Buy one left and one right. At 15F nights - you want a 5F or 0F rated sleeping bag. Or a 15F bag plus a liner for the colder nights. Are you sure you want a traditional mummy bag? I personally prefer down quilts. They pack smaller and are more comfortable than my mummy bag. They also work well when 2 people are together. Snuggle under the blankets, but then go into your own cocoon for the night time. **What is your budget?** It looks like Mountain Hardware does mens zippers on left and womens zippers on the right. * [https://www.rei.com/product/235362/mountain-hardwear-bishop-pass-15-sleeping-bag-womens](https://www.rei.com/product/235362/mountain-hardwear-bishop-pass-15-sleeping-bag-womens) * [https://www.rei.com/product/235363/mountain-hardwear-bishop-pass-15-sleeping-bag](https://www.rei.com/product/235363/mountain-hardwear-bishop-pass-15-sleeping-bag) Nemo does the same: * [https://www.rei.com/product/228439/nemo-disco-15-endless-promise-down-sleeping-bag-womens](https://www.rei.com/product/228439/nemo-disco-15-endless-promise-down-sleeping-bag-womens) * [https://www.rei.com/product/251886/nemo-disco-15-endless-promise-down-sleeping-bag-mens](https://www.rei.com/product/251886/nemo-disco-15-endless-promise-down-sleeping-bag-mens) This is a unique option too: * [https://www.rei.com/product/231206/sea-to-summit-ascent-15f-sleeping-bag](https://www.rei.com/product/231206/sea-to-summit-ascent-15f-sleeping-bag) The North Face Cat's Meow was the one I had with L/R zips. But it looks like they took that feature away. I was also going to recommend the Kelty Cosmic Down as a cheap/budget option - but they also look to only sell right zip bags.

i run cold and don't love the leg constriction of a mummy. i recently purchased a nemo disco 15 (women's long) and used it on a desert backpacking trip last month. one of the nights was stormy and temps dropped well into the teens and i was actually HOT and had to open the vents to cool off a little. it's heavy (3.5lbs) but i loved it so much for how well i slept that night.

I have the women’s disco 15 and enjoy it. It’s roomy and comfy as a side sleeper. There’s a pocket to put a pillow or stuff with a jacket. And it keeps warm without overheating. I run cold so I pair it with a s2s liner.

The new version of the Disco 15 Men's Regular has an advertised compressed volume of 6.4 liters. The Disco 15 Women's Regular is listed at 8.8 liters. So a little over 15 liters combined.

I have had a nemo disco 15 bag, two EE and now a Zenbivy 10 degree light bed with half sheet. The Zenbivy is by far warmer than EE and to the moon and back more comfortable than EE and the Disco. I was skeptical of Zenbivy but it is a quality product. I use a Ultra 3R exped pad for three season and a 5R in cold season.

Nemo disco 15 (-4 comfort) with a sss thermalite reactor in winter. Can open its ‘gill’ things in warmer temps so its not too hot. Such a versatile, roomy bag and packs small.

I have 2 Nemos. I love them.

I have the Nemo Disco 15 down sleeping bag and LOVE it. The Nemo bags are designed for side sleepers as they’re less constricted. Also, I’m a tall female (5’10) and most women’s bags tend to be too short for me. I suspect the men’s bags also have that extra length. Nemo makes both down and synthetic bags…I used to have a synthetic one and I liked it, but the down one is lighter and warmer. Also, I tend to get very cold at night. I have circulation issues and my feet will end up ice cold. The Nemo disco 15 with a warm rated sleeping pad has kept me good for the most part.

I recently went camping in 14-degree weather with the Nemo Disco 15. Generally the “comfort” temperature of a sleeping bag is 10-15 degrees higher than the listed rating, so I supplemented it with a down quilt on top and wore a wool base layer plus a light down jacket and a hat and double socks. I stuffed a wool sweater in the bottom of the bag around my feet. The only issue I experienced was that my air sleeping pad, which is insulated with an R value of 5, started feeling cold. It couldn’t compete with a temperature that low. Fortunately I had layered it on top of a closed cell foam z-fold pad, so I just let the air out and was ok. In the future I would probably put a quilt under the sleeping bag. All that said, my son has a Kelty Cosmic 0-degree bag, and he said he was toasty warm the same night. It’s a pretty good value for what it is.

Nemo disco 15!

I'm a 230 lbs 6' 3" guy and this is a great bag for me. Used in 19F and it was warm. I am a side sleeper so the ability to turn helps a lot.

Love my Disco 15. I'm 100% a side sleeper and I'm often riding up around the frost line even in the middle of summer where it still gets pretty cold at night.

Large quilt can work well. Also check Nemo Disco 15- it's built quite wide for side sleepers and has extra room around the hips and shoulders, should be plenty big enough and it's a great bag. Price is closer to $300 though iirc

I am a side sleeper and I vested in a Nemo Disco 15 and I've never been more comfortable in a bag. They widen out the foot box a lot, I also have wide hips and shoulders and have no issues rolling 360 inside the bag

I love my Nemo down Disco 15 Sleeping Bag . Best sleeping bag I ever had. It is packed small and lightweight and super spacious.

Nemo Disco 15, long, works great. Wife loves hers. Currently shopping for a Katabatic quilt. Reallyyyy want one of those.

I sold my old bag and got a Nemo Disco 15 and I love freaking love it. The 30 probably would have been fine for me, but I was icy in my old bag (which was a “nicer” Big Agnes 26) so I thought I needed the 15. Even though it’s a little heavier, as a toss and turn side sleeper whose knees and ass used to compress the sides of my mummy bag it’s DREAMY to sleep in. If you toss and turn less, they have a narrower spoon shaped bag called the endless promise that a bit more expensive but lighter (tho the difference really only shows up in the longer versions)

It should work fine, but keep in mind Nemo bags run a little cool because of their roomy cut, especially if you’re on the skinnier side. Filling the empty space by stuffing your static insulation in there with you can help a bit.

I have the Nemo disco and am a big fan, was very comfortable in it with an r4 pad when I was out in 25F/-4c sleeping weather

I really like the Nemo Disco 15. Roomy and light. I’ve been using it for years.

It’s fucking cold at night at the higher elevations…like frost on your then cold. But more important than temperature rating is the type of sleeper you are. I can’t stand mummy bags, and so use a Nemo Disco 15f for side sleeping.

Based on your criteria of comfort, I would recommend the Disco over the Coda because the cut of the Disco is spoon shaped, which is roomy. I have one and it’s my go-to bag in the cold. I can’t speak to the other bags, maybe someone else can comment on those.

I’ll second this. While a bit on the heavy side if you are backpacking, it isn’t prohibitively so. I’m old now and I value comfort/sleep over a few ounces. The spoon shaped bags by Nemo are comfortable and perform in the cold, and the price is decent for a quality bag. I also view the Nemo Tensor All-Season as the best all around sleeping pad on the market. There are a couple options considered a bit more comfortable (namely Rapide SL and Neoloft) but they can’t hold a candle to the warmth, packability, and weight of the Tensor. It checks all the boxes (except inexpensive I guess).

Bought a disco 15 and used it this weekend on my first trip in years. It was fantastic. I think a quilt will be a later purchase for me. I like the snug feel of a sleeping bag.

It’s all about a good sleep system. I have a 15 degree Nemo bag and an XTherm pad. Throw in a hot water bottle and I’m toasty all night. Just sleep in a base layer.

5'5 hot sleeper here in the cascades! I had a nemo 35 and 15 and ended up getting rid of the 35 bc if I ever has doubts about temps dropping and getting too cold I would just always pack the 15. Can always lay on top or stick a leg out if too hot but I find myself often running into colder temperatures at night at higher elevations.

I love my disco. The shape is soooo much better than a mummy shape

Nemo Disco is the way to go.

I have a disco and its pretty good used it like a quilt so often I ended up going for a quilt, Specifically a zenbivy, its also good, I set it up with one side fixed to the sheet and the other mostly free. Like sleeping in a bed.

I can confirm that the nemo disco is down, reasonably light and compact, and zips together. I can also confirm that you don't have a whole hell of a lot of room in the combined bag, and if you're a twitchy sleeper - I am - the person sharing the zipped together bag will probably regret that choice before morning.

NEMO Disco or quilt. Edit: I mean, yes the Disco is a mummy-style bag, but iif the mummy bags you've tried up until now aren't working for you, it might be because they don't fit rather than the type of bag they are. Guessing you might like it if you tried it. I toss and turn too, and this is the most comfortable bag I've ever owned.

Buy a second bag of the same model and brand . ZIP them together and make a single into a double bag. It’s a game changer!

I used a nemo disco for a while and it was ok. Now I use a zenbivy quilt and won't go back to a bag.

That's surprising, the disco has plenty of tossing around room. I would definitely suggest switching to a quilt and comfy thermals.

Nemo disco

Correct. Disco and Riff both come in 30*F and 15*F. But the riff uses 800fp down and the disco uses 650fp down so the riff is their ‘ultralight’ version it’s a bit narrower and lighter weight.

Also a side sleeper who tosses and turns all night. I love the Nemo Disco and now have 2, a 15 and a 30 in down. I use at least a 3” thick pad. I rarely use the hood part of the mummy and it’s been fantastic.

I was also going to suggest the Nemo Discos, you beat me to it lol. I'm pretty sure most manufacturers make it *possible* to connect their mens/womens bags with the opposite-side zipper just on account of using the same zippers, but Nemo are the only ones I recall advertising it as a feature. It would certainly be a good place to start.

I have the Nemo Disco and love that thing. I am 5'9 and 200lb and toss like fish on a hook at night..lol. I do strictly car camping and wanted something lighter than my old Teton sleeping bag without much restrictions. After reading many reviews, I opted for the Nemo.

I’ve got a nemo bag goes down to -9c Nice bag 600 fill down so jt compresses well, and good for side sleepers, I think it’s called the disco. They have a similar one with 800 fill so it’s even lighter and more compact as well

Ya it’s a nice bag. Had it for a few seasons now down to about freezing and I get through the night fine

I’ve never had an issue with it at zero. I haven’t taken it down to lowest levels of the rating. I also have a r4.5 sleeping pad, I sleep in smart wool top and bottom and use a sleeping bag liner. The liner I’ve always used simply because it’s easy to clean and keeps my bag from getting dirty.

Smart. Anyway In general I do believe the Nemo is a bit cooler than some because of the shape which means more air space. I guess it's the downside of allowing comfortable side sleeping.

Love my Nemo Disco!

I have the disco as well and I love it. I use the Nemo Jazz for car camping and the disco for backpacking

Thank you! Originally I had ordered a cheap sleeping bag off Amazon, but then I got to thinking that they might be called in Algonquin. So I ordered the disco. It was on sale at MEC. I like it because it's a little bit wider than the mummy ones. It's worth the investment to me to be warm!!!!!

OH MY GOD I went on my first every camping trip to Algonquin this weekend and the Nemo Disco SAVED MY LIFE!!!! It poured rain for 14 hours straight :(:(:(:(:(:( But the sleeping bag kept me warm thank GOD. It was my saving graces TBH. My tent was leaking a bit so the bag got a bit wet but still kept me warm. Pulled it over my head and snuggled in. This weekend was a very serious initiation. It can't get any worse than the deluge we experienced lol.

For clarity - The Riff (and Disco) are down. While the Forte and Tempo are synthetic. Their spoon/peanut shape is definitely very popular with side sleepers, or people who sleep angular or toss and turn. Much more forgiving than a regular mummy, without the draft issues of a quilt. Recommend people getting into quilts, to buy a wide one. This will help mitigate drafts. You mention REI, all of their sleeping bags now come in "wide" versions. Still a mummy for the most part, but about 5" wider than a regular mummy. Their Magma is an excellent bag, as is their Magma quilt, but it's only rated to 30 degrees.

Nemo Disco sleeping bags have “gills” you can open to vent. They keep me cold when I am ice camping in the winter and I open the gills to vent when it is warmer. In the summer I often sleep with the zipper open or on top of the bag if it is very hot, but I recommend the Nemo Disco as a versatile option for almost any temperature.

I see Nemo has been mentioned a lot, which is what I came here to suggest for a sleeping bag with a Klymit sleep pad. We do a lot of tent camping each summer. Some pack in, some drive in, some canoe in, but always in a tent and always on the ground. As we’ve aged I have been concerned we wouldn’t be able to continue sleeping on the ground, but the Klymit has never let us down. We’ve had our pads for over 11 years and only this year did we finally “upgrade” to the wider version. For sleeping bags, the Nemo spoon, down filled was our choice. Lightweight and has been excellent for MN camping. Good luck!

I’ll second the cut of the Nemo “spoon” bags—way more comfortable than a mummy. I’ve also found that looking for mummy bags with a wider shoulder girth helps (I’m not too big, but I’m a side sleeper and I toss and turn). For example, I bought a 10F down bag from Feathered Friends with a 64” shoulder measurement and that made a huge difference. What’s the range of overnight temps you’re sleeping in, and what are typical temps during the time of year when you camp most frequently? What’s the R-value of your sleeping pad? What are you wearing for sleep clothing, and are you wearing a hat? What’s your budget? You can potentially cut some cost and weight by going with a 15F or 20F bag, but that depends on the rest of your sleep system. If you’re already using an insulated sleeping pad and are still cold, a lighter bag might not be an option. If you don’t use an insulated sleeping pad, though, that’s an upgrade you can make that’ll help with warmth. Ditto for thinking about what you’re wearing to bed. My apologies if this is all stuff you’ve already considered, but having a little more info might help others make recommendations here.

Quilts, semi rectangular bags (Sea to Summit Trek and Ascent Down) or the Big Agnes Sidewinder series are what you want. The Nemo Spoon series of down bags are also quite roomy. I sleep on my side. I use Hammock Gear Econ Borrows most of the time and I have a Marmot Col -20F bag for anything 20F and below.

Also a side sleeper and I have been a fan of the Nemo spoon bags

I’m a stomach/side sleeper and love my Zenbivy quilt+sheet and their matching pillow system, but it’s quite an investment for a casual camper. I’d recommend looking for a cheaper quilt or even a rectangular sleeping bag on Amazon or Decathlon if you’re not looking to spend a lot. I was really unhappy with my spoon shaped Nemo sleeping bag. Even though it’s wider than a traditional mummy bag, it was still restrictive. There are a lot of other spendy quilt brands out there and most have already been reviewed on r/ultralight.

I like the spoon shape of the Nemo bags. And, I’m currently using a wide deluxe pad from Big Agnes.

Which 2 in 1 are you referring to? The ones that come to mind would exceed your budget, but examples help.  What temperature are you expecting at night?  Mainly, I would suggest finding an insulated sleeping pad with a stated R-value. Depending on how cold it will be, the R-value changes (higher R for colder temperatures). For sleeping bag, add at least 10°C, so for example, if you expect overnight temperatures around 5°C, find a bag rated for -5°C.  I have a Nemo Quasar insulated pad in the double width (I move a lot), and a Nemo sleeping bag (in their "spoon" style because I can't sleep in a mummy style bag). 

I vote for Nemo bags. I have 2 and love them. Perfect for side sleeping.

Nemo for sure

Spoon shape is great, arm zippers in the boost just seem drafty.

Check backcountry and steapncheap. I got 2 500$ Nemo bags for 200$ a couple years ago.

Nemo sleeping bag with REI 2.5 self inflating sleeping pad works for me.

Never tried a quilt, but as a fellow side sleeper I LOVE my Nemo sleeping bag. Can't believe I ever tried to use a mummy bag.

Love my Nemo down bag. Love.

I have a Nemo down sleeping bag. It’s a mummy but the shape is roomier so I can flip around onto my side or stomach. There are “gills” in case you need to cool down a bit. Hood is very puffy. I’ve used it in autumn (Ontario) with thermal liner when outside temp was just above freezing and I was warm and slept great. Also used it in the Maritimes in summer (strong cool winds and heavy rain) and it was fab too. The bag is very cosy and I really love it.

Budget is a factor, as well as intended use (backpacking vs ultralight speed hiking) Down will be lighter (and more expensive) than synthetic fill I have a Nemo bag and a few different thermarest pads depending on the season I also have a couple Big Agnes (they are great for bigger people) bags, but they do not have any fill on the bottom, instead they rely on the sleeping pad. There's a whole interesting theory about this design if you care to research it! You can talk to the folks at Hiker Direct and they are big supporters of scouting. We've got folks that have really good luck with Nemo, Kelty, Hyke and Byke (online sales only), and some others, too. GearLabs reviews is pretty thorough if you want to really dive into the numbers and test process before you buy.

I want a rumpl down blanket! It looks like a lifetime buy. I have a Nemo sleeping bag. Light and great quality. Recently I have been seeing great things coming from them. Pricey though. My Pendleton’s would agree with using wool. I prefer white fuel stoves and lanterns. Coleman of course.

Nemo bags are extra roomy yet pack down tiny. Love mine wouldn’t use anything else

We use nemo sleeping bags. They have male/female mummy bags with zippers on opposite sides. They can be used solo or in tandem. Other commenters are right, when cold it’s much more cozy to use them solo without the gap between shoulders

Nemo sleeping bags are designed to zip together, highly recommend. I like having the option to conjoin if it’s cold out, but sometimes like to unzip in the middle of the night and have my own space

I had the same problem. Bought a Nemo something which had a wide center. It helped but I still couldn’t sleep. I switched to a quilt that strapped around a pad (enlightened equipment I think) and it is an absolute game changer. Super roomy and very warm. I mean I still don’t sleep but it is no longer because of the sleeping bag.

I have a Nemo bag and pad and have been quite happy with them both. Particularly if you're a side sleeper or otherwise restless, the Nemo spoon-shaped bags are great. They're not the lightest but they're light enough if you need that comfort. I suggest adding the Big Agnes Rapide to your list of potential pads.

I agree that quilts are probably one of the strongest directions here. If you can stand sleeping bags then lots of Nemo bags have a spoon shape that really lets your shift your legs around which as a side sleeper I really liked.

Go to REI, invest your money on a good Nemo brand sleeping bag. You’ll be thankful for many many years and if anything happens to it you can return exchange at REI for years. If you haven’t already sign up for a REI co op membership and get your % back on your purchase.

My order of preference, without prying more info out of you would be: 1. Magma 2. Radiant 3. Nemo … anyone giving you numbers after the name of the bag is guessing because you never mentioned what temperature rating you need and what geography we are talking about. In terms of r-rating we would need to know what mattress pad you are shlepping too…
