The Nano Quilt design is simple, clean and lean. For experienced quilt users looking for the lowest bulk and weight.


Backcountry quilt style design with fully enclosed foot area.

Optional top neck drawcord closure with corner snaps.

Narrow baffle pattern for enhanced down control.

Ultralight draft controlling under-body shock cord straps. 


Custom sizing is geared towards efficient use of materials to keep the weight at an absolute minimum. 

The Nano Quilts width options are true to size, but overall offered in narrower numbers than the fully featured Arc UL Quilt.

Rating and efficiency:

It takes a savvy backcountry traveler with prior quilt experience to push the Nano Quilt to it's advertised lowest comfort rating. This is due primarily to the lesser coverage. But also lack of draft collar and ETC System; and regular 'horizontal' baffle layout in the torso region plays a role. 


Minimalist Wonder

No frills, lofty, warmth defies weight. Meticulously sewn, packs small. Nunatak products now make up my entire sleep systems, from 50 to 15 degrees.


Light as a Feather

This June I started using my Nano Summer Quilt, Custom 40°F, Size small 52" shoulder to hips width 38" foot. Weighing in at 12.94oz I hardly know it’s in my pack. Used for 10 nights so far and in temperatures ranging from 55-45f overnight, it has kept me nice and warm. I always worry about size and quality when ordering form overseas but Nunatak always gets it right with size and great quality of workmanship. I can see the Nano being my go-to quilt for summer backpacking adventures.
