From Blanket to Quilt
In it's basic rendition the 40° Nano Pro 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" box baffled construction. 900 FP down.
Stepping up in features from the comforter mode gradually evolve the Nano Blanket Pro 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.
The next step is further sealing of the foot end. At another 14 grams, this mod enables a convertible footbox, easily switching from fully open blanket mode to enclosed warmth.
The underbody straps many quilt owners use to control drafts complete the upgrades needed to turn the basic Nano Pro 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 Pro 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!!
When choosing any of the optional closed foot end features, consider adding at least 5" to the length to ensure adequate coverage.
The Nano Blanket Pro substitutes the regular shell material with a super light Robic based weatherproof fabric to one side of the fully reversible quilt.
Face this micro-porous, waterproof/breathable shell out towards the elements to ward off mist, spray and dew in an open bivy or brief recovery stop.
Face it in towards the body to achieve a mild Vapor Barrier effect. This will keep moisture from damp sweaty clothes from migrating into the down, and will also boost the temperature rating of the Nano by a few degrees. Adventure racers and endurance bike riders will appreciate this fast and simple method of quickly resting without compromising the insulation.
A second shell available is the 1.4 oz/yd 10d ripstop-PTFE laminate. This Gore-tex like material offers better moisture protection and enhanced breathability compared to the Robic above. An obvious win-win situation was it not for the increased weight and bulk associated with this. Read more here regarding fabric choices.
The 0.66 Membrane 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.
For the Nano Blanket Pro only Hyper-Dry moisture resistant down is offered. With a waterproof/breathable shell there's an increased risk of moisture condensing on the inside of the shell fabric during certain conditions. Having the added protection of treated down makes sense.
