Spoon Form

The Disco 15 is a spoon-shaped mummy sleeping bag, a modification to the normal mummy form invented by NEMO, for aspect sleepers. It has an hourglass form that’s extensive throughout the shoulders and toes so you may flip round contained in the again with out feeling encumbered.  The contour follows the standard vary of movement of the knees and shoulders.  Not solely is the spaciousness a profit for sleeping positions, however the additional elbow room additionally makes altering positions a lot simpler than a standard match.

The disadvantage to the extra beneficiant minimize is clear: a bigger bag means extra materials and extra fill to insulate it, and the bigger inside quantity signifies that it takes longer to heat up.  Whereas the Disco 15 compromises properly between spaciousness and weight, there’s undoubtedly a tradeoff which will tip the scales an excessive amount of for individuals who begrudge each additional ounce of their pack.

One other issue contributing to the consolation of the Disco 15 is its smooth lining.  The taffeta materials avoids the slickness of many sleeping bag materials, and it feels nice to the contact.  As an added bonus, the inside and exterior materials is comparatively freed from crinkles and rustles, making for a quieter evening’s sleep than many luggage present.

Sleeping Bag Building

The NEMO Disco 15 is insulated with 650FP down fill that has a hydrophobic coating to withstand water.  The down is RDS-certified as responsibly sourced and is PFC-free.  This alternative of fill materials retains the load sufficiently low to be a backpacking bag whereas maintaining the price down. As compared, a 15 diploma down sleeping bag insulation with 800+ fill energy goose down can price 50-75% greater than the Disco 15. That’s a sizeable sum of money.

Draft administration is neatly dealt with by the Disco 15.  A full-length draft tube prevents lack of warmth alongside the zipper, whereas a flap of down that NEMO calls a “Blanket Fold” replaces a mummy bag draft collar with a flap of insulating materials that may be pulled inside to forestall warmth from escaping across the higher chest or folded exterior to vent extra heat.  It’s an important function, that’s intuitive and straightforward to regulate in the midst of the evening.  In case you’ve ever struggled with a mummy draft collar at evening, you’ll admire it. When mixed with the drawstring closure in conjunction with the face opening, the bag’s temperature might be properly fine-tuned.

NEMO  has additionally included what they name “Thermo Gills” to the highest of the sleeping bag over the torso which might be unzipped to launch extra warmth.  Two zippers working lengthwise on high of the bag enable air flow within the torso space with out exposing the inside of the bag to drafts.  They work very well, offering simply the appropriate cooling after I was too heat.  This extends the helpful temperature vary of the sleeping bag to hotter nights than could be snug in the same bag.  The one factor I didn’t take care of with the Thermo Gills was that the zipper pulls had been small, tapered, and barely slick, which made them exhausting to find at midnight and use with gloves.

Temperature Ranking

The Disco 15 makes use of the brand new ISO temperature score normal (ISO 23537-1:2016, for all my fellow nerds), which supersedes the EN 13537 score beforehand used.  This testing resulted in a decrease restrict of 14 levels Fahrenheit. This places the Disco 15 firmly within the shoulder season class, able to dealing with cool spring and fall nights however in all probability not a chilly winter one.

The bigger minimize of the Disco 15 makes it extra susceptible to barely hotter or cooler zones inside the bag, particularly across the legs while you transfer them round.  It is a signal of the design tradeoff between extra space and heat retention; a bag with out room to maneuver has no such zones however is extra confining.

Anti-Snag Zipper

One top-notch function of the Disco 15 is the high-quality zipper that includes an anti-snag plow.  This design virtually completely eliminates snagging, which not solely saves annoyance but additionally protects the shell of the sleeping bag from rips and holes that trigger leaked insulation materials.  I used to be in a position to make use of the zipper in any respect angles, with each fingers, at midnight, and in a wide range of positions and not using a single snag.  The zipper has a gusset at each ends to maintain its steel away from heat pores and skin on a cold evening. The boys’s mannequin, obtainable with left zipper solely, can also be in a position to hook up with the right-zippered girls’s mannequin for a double sleeping bag.

Extra Considerate Options

Ever woken up at 3 AM with chilly, moist toes as a result of the footbox of the sleeping bag was touching the within of the tent and absorbed condensation?  That’s not a enjoyable expertise!  The Disco 15 includes a waterproof/breathable footbox to forestall this case, which is a very nice contact as a result of not solely are moist toes uncomfortable however permitting them to be dry at evening alleviates maceration and helps the pores and skin be much less blister-prone.

When the temperatures drop, maintaining batteries heat is essential to protect the efficiency of the chemical reactions that ship energy.  The Disco 15 has a small pocket over the left shoulder that may retailer them in an insulated spot.  The pocket was adequate to retailer a telephone, a USB energy pack, and some AAs.

One other function I significantly like on the Disco 15 is the pocket within the head space that may maintain a pillow or be full of clothes for additional padding under the pinnacle.  This retains the pillow firmly in place no matter twists and turns, and it’s in the appropriate place to offer correct help to the pinnacle.

Comparable Down Sleeping Luggage


The NEMO Disco 15 sleeping bag presents luxe comforts, prolonged versatility, and well-considered design, at the price of elevated weight.  It’s an important alternative for the aspect sleeper or those that really feel confined in a mummy bag.  Its thermal regulation options prolong its vary, making it a sensible choice for an extended journey that has each hotter and chillier nights.  The additional touches of the pillow pocket and waterproof/breathable footbox present NEMO’s consideration to element.  Whereas heavier than many comparable luggage, the additional weight could make the distinction between getting a cushty evening’s sleep or not, particularly if you happen to’re a aspect sleeper.
