Spoon Form

The Disco 15 is a spoon-shaped mummy sleeping bag, a modification to the standard mummy form invented by NEMO, for aspect sleepers. It has an hourglass form that’s large throughout the shoulders and toes so you may flip round contained in the again with out feeling encumbered.  The contour follows the everyday 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 conventional match.

The downside to the extra beneficiant lower is apparent: a bigger bag means extra materials and extra fill to insulate it, and the bigger inside quantity implies that it takes longer to heat up.  Whereas the Disco 15 compromises effectively between spaciousness and weight, there’s positively a tradeoff which will tip the scales an excessive amount of for many who begrudge each additional ounce of their pack.

One other issue contributing to the consolation of the Disco 15 is its gentle 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 baggage present.

Sleeping Bag Development

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 burden sufficiently low to be a backpacking bag whereas retaining the price down. Compared, a 15 diploma down sleeping bag insulation with 800+ fill energy goose down can value 50-75% greater than the Disco 15. That’s a sizeable amount of cash.

Draft administration is well 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 stop warmth from escaping across the higher chest or folded exterior to vent extra heat.  It’s an amazing characteristic, that’s intuitive and simple to regulate in the midst of the evening.  In case you’ve ever struggled with a mummy draft collar at evening, you’ll recognize it. When mixed with the drawstring closure along with the face opening, the bag’s temperature could be properly fine-tuned.

NEMO  has additionally included what they name “Thermo Gills” to the highest of the sleeping bag over the torso which could be unzipped to launch extra warmth.  Two zippers operating 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 rather well, offering simply the suitable cooling after I was too heat.  This extends the helpful temperature vary of the sleeping bag to hotter nights than could be comfy in an identical bag.  The one factor I didn’t take care of with the Thermo Gills was that the zipper pulls have been small, tapered, and barely slick, which made them laborious to find at the hours of darkness and use with gloves.

Temperature Ranking

The Disco 15 makes use of the brand new ISO temperature ranking commonplace (ISO 23537-1:2016, for all my fellow nerds), which supersedes the EN 13537 ranking 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 most likely not a chilly winter one.

The bigger lower of the Disco 15 makes it extra liable 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 characteristic 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 in addition protects the shell of the sleeping bag from rips and holes that trigger leaked insulation materials.  I used to be ready to make use of the zipper in any respect angles, with each palms, at the hours of darkness, and in a wide range of positions with out 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 lads’s mannequin, accessible with left zipper solely, can also be ready to hook up with the right-zippered ladies’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 encompasses a waterproof/breathable footbox to stop this example, 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, retaining batteries heat is necessary 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 enough to retailer a telephone, a USB energy pack, and some AAs.

One other characteristic I notably like on the Disco 15 is the pocket within the head space that may maintain a pillow or be filled with clothes for additional padding under the top.  This retains the pillow firmly in place no matter twists and turns, and it’s in the suitable place to offer correct help to the top.

Comparable Down Sleeping Luggage

Advice

The NEMO Disco 15 sleeping bag affords luxe comforts, prolonged versatility, and well-considered design, at the price of elevated weight.  It’s an amazing 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 good selection 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 baggage, the additional weight could make the distinction between getting a cushty evening’s sleep or not, particularly in the event you’re a aspect sleeper.
