Nano Blankets are specialist tools with room for broader appeal.
SUL (Super UltraLight) hikers go fast and far; but sleep very little. A full base kit might weigh under 5 lbs. The Nano Blanket in 40° is pure SUL. Extensive custom options are offered to dial in critical details.

40° rating, super compact stuffed size, ultralight. Versatile, essential, inspiring. SUL.
From blanket to quilt
In it's basic rendition the Nano is a tapered rectangular backcountry comforter made with gossamer light fabrics and high fill power goose down.
It is as light and compact as is currently possible. All clutter has been removed. In this configuration there's no Velcro, no shockcords, no snaps. Only pure function remain: 0.66 ounce per square yard Membrane shell and liner. ¾" baffled construction. 900 FP down.
Stepping up in features from the comforter mode gradually evolve the Nano Blanket towards full quilt mode, based around the original 40° rating. Shockcord channels can be added at the foot end or top end, or both. Using specially sourced 1/16" shockcord and minimalist cord locks each channel adds about 12 grams, depending on blanket width.
From here an up and down 24" strip of Velcro is the next addition. At 14 grams, including other SUL hardware, this mod enables a convertible foot end, easily switching from fully open blanket mode to enclosed footbox.
The underbody straps many quilt owners use to control drafts complete the upgrades needed to turn the basic Nano to a full Nunatak quilt. However, in a nod to SUL philosophies, these are merely comprised of 1/16" shockcord and tiny captive cordlocks.
The Nano Blanket is custom built with 8 lengths and 5 shoulder widths available in any combination. Add to this three foot end sizes. And, if these 120 sizes are not sufficient for you - just email us!!
The 0.66 Membrane shell and liner fabric is optimally suited for an application like this. Few, if any, materials on the market today are as light as Membrane. Being a taffeta style fabric without the bulk and weight concentrated in a ripstop grid, the overall resistance to wear is very good for such a thin material. Two colors of Membrane are offered, both on the darker side to aid in heat absorption and drying: black and an attractive dark blue.
0.8 Pertex Quantum shell fabric in Mountain Safety Orange is available for applications where ultimate hi-viz is desirable. Fractions of an ounce heavier than Membrane, this fabric is very bright, aiding in rescue situations. The Pertex is also offered in green and black.
Select 900 fill power down for lightest weight and bulk. Only white goose down used - responsibly sourced and of the highest quality. Choose between regular and Hyper-Dry moisture resistant varieties.
Weight and Bulk
As there are so many possible size combinations, we are only going to give an accurate real life weight of one style of Nano Blanket:
75" long times 48" wide with a 34" wide foot end is 10.6 oz, and fit inside a Nalgene bottle. Wide mouth, that is!
Based purely on calculations one of the biggest, the absolutely massive version of 95" x 66", with a 42" foot should weigh 17 oz, and the smallest, barely useable Nano Blanket (60" x 42", with a 34" foot) about 7.7 oz.
The silnylon stuff sack supplied is 11 grams.
