QUILT COMPARISON CHART AVAILABLE

The Nano Blanket technology is here expanded to create a super ultralight (SUL) two person sleeping quilt. Unlike the basic one person Nano Blankets, this Dual quilt has a fully formed and enclosed oval footbox, measuring 20" across.

At 40° comfort temperature (wearing long johns and thermal zip neck top) this quilt is limited to summer use in the mountains. Made for so-called fastpacking and FKT attempts, every design decision of the Dual Nano quilt is focused on low weight, low volume and utility. Split between two people, the Dual Nano (in size 73") represents 10 oz per person. This is light for a full sized sleep system!

Sizing

Offered in 8 length sizes from ultra short (for potential chest high use combined with a down hoodie) to really long. The width is the standard, and very adequate, 78", while the foot section taper down to an oval, fully enclosed box.

Like all Nunatak quilts these numbers are true; i.e. the quilt does not need to be stretched before measuring.

Options

For the Dual Nano there's only the lightest fabrics available. Colors are black, blue, green in the regular super-breathable materials.

A waterproof/breathable shell is also an option, namely the grey Robic ripstop from our Pro Series of products. Choosing this does not add weight, nor bulk, but it does boost the temperature rating a few degrees. The Hyper-Dry moisture resistant down is best combined with the Robic shell, due to the slight risk of condensation in certain conditions.

Down Overfill

Additional down (overfill) is also available. Why this? The way athletes respond to cold and fatigue varies from person to person. The 40° rating will feel adequate to most, too warm to some and not warm enough for a few. If you know you sleep cold, or are concerned about environmental influx specific to your use, consider adding down.

Quilt Straps

The Dual Nano comes stock with a SUL specific set of minimalist two person quilt straps, fully removable and adding only 12 grams. A full fledged set of standard quilt straps can also be added to the order. With this option the SUL ones can still be installed.

The length of the pad attachment strap allow you to use two fair sized pads, each of maximum width of 28". A special buckle holds the strap in place in the middle between the two pads. 

The top edge of the Dual has an additional retainer strap that allow easy exit and control, individually side to side.

Weights

The Dual Nano in 73" length weighs 20 ounces, of which 11.5 ounces is down. The various shell fabric options have only little impact on the weight.

Adding the SUL quilt straps is 12 grams. The full fledged standard strap package is another 40 grams.

Changing the overall quilt length is about an ounce for each of the optional 5" increments offered.

Nano Couple Quilt, 73L, 78W, 20 foot

From an email we received: The quilt worked great, and I mean really great. The larger foot box was very welcomed. We had plenty of room for our feet. There was ample room to pull the quilt around our shoulders. It was the right amount of down. We were able to use it in the conditions that we hiked in, which were low temps in the 50’s and high temps in the 70s. Any more down would have been too warm. I’m a warm sleeper and my wife is a cold sleeper. The down was just right. Thanks again for all of your guidance and suggestions. Your input was very appreciated and resulted in a perfect 40 degree bag.

    Down Type
    Choosing Hyper-Dry moisture resistant down will help combat the effects of perspiration, misting tents and damp air. Nunatak products made with Hyper-Dry down will have a slight increase in bulk over those made with regular down. In some instances they may contain an additional 5% of fill weight.
    Down Overfill
    Cold sleeper? Consider adding a few ounces of extra fluff.

    The SUL straps are 1/16" shockcords and tiny cordlocks, and includes 2 under-the-body cords and a top cord. Total weight is 12 grams.

    The full strap set is of 3/4" thin webbing with buckles and weigh 40 grams for the 3 units included. Selecting this method still includes the SUL option. Switching between the two systems is simple.
