  • Pull the slipcover over two 20-in.-wide sleeping pads (sold separately) to create a full-size bed, and then fit the Tango Duo Sleeping Bag onto the pads
  • Sleeping bag attaches to the pads by sliding the head and foot sleeves over the ends of the pads to create a full-size backcountry bed
  • Backless design of the Tango Duo sheds ounces, keeping it under the weight and volume of a typical one-person sleeping bag; hood snaps off to save even more weight
  • Mates perfectly with two NEMO Cosmo™ series sleeping pads (sold separately); will work with most other 20-in.-wide pads
  • DownTek™ 700-fill-power duck down repels water by employing nano technology and a proprietary process to apply a micro-thin polymer to the down
  • DownTek down repels water and maintains loft and insulation value, even in the wettest conditions
  • Proprietary application process creates a water repellent, antimicrobial and antibacterial down insulation that actually floats on water
  • Waterproof/breathable coating on the backside of the fabric combines with a Durable Water Repellent on the exterior to protect from tent wall condensation
  • Box-baffle construction keeps down from shifting around, so cold spots are prevented

Rated 5 out of 5 by from Fantastic 2 Person Bag This sleeping bag was given to my husband and I as a wedding gift. We have already used it several times, and love it. It is extremely light-weight and fits into the stuff sack of my mummy bag. I do recommend a slip cover to accompany it, as it keeps the pads together. I made one, but if you aren't sewing inclined, the matching slip cover looks nice. It's very warm for how light it is, and since it's essentially a comforter, it's very easy to adjust how much you are covered and regulate temperature. It stays in place very well, and is a lot more comfortable than a mummy bag.

Rated 5 out of 5 by from Best Double Bag! My wife and I bought this sleeping bag about a year ago. We spent 8 nights in the Sierra Nevada's backpacking the High Sierra Trail. This bag was perfect for us! It was great to eliminate the weight and space of two bags and we were able to cuddle every night. We did not use the NEMO sleeping pads that it recommended, but we used two REI Stratus Sleeping Pads, which worked just fine. They didn't fill the sleeping pad cover completely, but we still slept very comfortably. The sleeping bag did a great job of staying dry and avoiding odors (which is important on a long trip!). It was also very comfortable to sit on inside the tent when we were just hanging out. While we were out there, temperatures dropped into the upper 30s and we were very comfortable. Since then, I have used it on another couple of night trip in West Virginia, where the temperatures dropped into upper 20s. Since my wife was not with me, I used it as a solo bag by just wrapping myself around it and slept great - very warm and light. I HATE mummy sleeping bags. I move around a lot in my sleep and like to change positions frequently, so this is perfect for me. Only con is that it is expensive. I would highly recommend waiting until you get your REI refund and a 20% off coupon to buy it...that is what made it affordable for us (and you would spend at least this much for two separate bags of equal quality).

Rated 3 out of 5 by from Cold but light It is not warm enough. This is only good down to about 40F, any less and you will be cold. The downfall of this system is that you lose tons of heat from the gap between yours and your partners shoulders. Additionally, the hood does not pull down far enough to provide any meaningful warmth for your head. That said, the system is incredibly light and with the slipcover is very comfortable. If you are sure you will not encounter temperatures below 40F, then this is a very good sleep system. Otherwise look elsewhere.

Rated 5 out of 5 by from Size of one bag for two My boyfriend and I have taken this on motorcycle camping trips and a backpacking trip. It's an excellent three season bag, the size of one sleeping bag, for two. It was warm down into the 40s, except he was cold one trip because he didn't bring anything to sleep in (I had smartwool base layers and was cozy). On our last trip I decided I would never go camping together without it. We use two REI pads (cirrus) in the Nemo sheet that hold them in place and they fit perfectly ( any pad that's 20x72 should fit). There's nothing like getting to cuddle in one giant sleeping bag with your love in the outdoors.

Rated 5 out of 5 by from Great option for summer backpacking couples I bought this as a light weight backpacking option for my girlfriend and I. It's a great set up that sheds a lot of weight and space on the trail. I recommend buying a smaller stuff sack to save space. I didn't purchase a slipcover but use a twin cover and it worked fine. Also, I use a mattress coupler (thermarest brand) to keep the mattresses together. We've used this bag in the Canadian Rockies about 10 times and it gets a little cool in the lower temperature ranges 1-5C and as recommended I wouldn't go any colder than that. Small compartments within the structure of the bag keeps the down exactly where it should stay. Hey Nemo! You guys should do a slightly warmer version (but still ultra light) for us backpackers who camp in cooler climates. I'd be happy to test it for you!

Rated 5 out of 5 by from Perfect for an ultralight couple! We love this sleeping system so much! It's cozy, has the feel of a real bed instead of the tightness of a mummy bag, and it's so light! Wouldn't trade it for anything.

Rated 5 out of 5 by from Awesome! I have had this for about two years now. I use it quite often, for sleeping on the porch in 50+ deg weather to using it as my conferter on my bed during cold winter nights. It is very confortable, great to have on the trail or car campong. Allows more freedom than any conventional or mummy bag out there. Note: I have not used this below 45deg but plan to give it a shot this winter. I'll post an update when I do. I am sure the single is just as great and for just over 2lb/s this has been awesome! Plan on bringing it on another trip in August.

Rated 1 out of 5 by from Not a sleeping bag Just got mine today and realized why it is so compact and light. It's not actually a sleeping bag but more of a blanket with slots to hold air mattress'. While we haven't used it yet, it's obvious that the sides will not hold in any heat. Basically I could have bought a rectangular bag for a fraction of the cost, cut off the zipper and used it as a blanket.

I have 2 klymit static V pads that are 23" wide.  Nemo list the slim for 20" pads and the regular is for 25" pads.  Which one would we go with?

Asked by: Jplippens
Because your sleeping pads are over 20 inches in width, the regular in the Tango Duo Sleeping Bag and Slipcover Combo would be the best bet.

At 41.3" wide, the Exped Synmat Hyperlite Duo would seem to work with the Tango Duo, particularly given the flexible nature of sleep pads. Is there something else incompatible with this combination (EXPED/NEMO)? Tapered shape of EXPED?

Asked by: GreginRI
The Nemo slipcover has 2 slots that are stitched in between. I got my 23" klymit in there, but that's it. The 40" would not work.

Does this double bag have no zippers at all?

Asked by: Imke
The Tango Duo Sleeping Bag and Slipcover Combo does not use zippers. Elastic is used to wrap the components around the sleeping pads.

The length of this bag is only 72 inches. My husband is 6'1". Do you make a long version?

Asked by: NicolePDX
The sleeping bag is designed to fit people up to 72" tall. The actual length is in the 80" range. At 6'1", your husband could still fit into this bag, especially since it has the extra width. We do not carry a long version of this sleeping bag.

I understand that this system works with 20" wide pads, but what length should they be? I want to make sure i find the best fitting sleeping pads to go with it. An REI link to the proper Nemo pads would be extremely helpful! Thanks in advance!

Asked by: Villalobosbrandon
The sleeve will fit a 20" x 72" sleeping pad. Here's a link to our selection:

I bought the Nemo Tango Duo this summer, like the idea, but my wife and I were cold, had to wear full clothing tho stay warm. I would like to buy another bag to put over existing bag. Can I bay a bag only?

Asked by: HLC - Red
Nemo does not make a bag that is desinged to slip over the Tango. You might consider a sleeping bag liner or travel sheet. In some cases these item can add an aditional 15 degrees of warmth to your sleeping bag.

What would be a good upgraded stuff sack for this bag?

Asked by: 4 Red Stars
The 11 liter REI Lightweight Compression Stuff Sack would be a good choice for the Tango Duo Sleeping Bag.
