The 3D is our highest developed quilt, designed to provide ultimate efficiency via draft free warmth and weather protection, while maintaining the adaptability and ease of use of the modern backcountry quilt.

The 3D was designed in a response to the luke warm reviews of the generic open bottom quilt when used in real cold conditions. While adequate loft is simple to achieve, it takes creativity to arrive at the necessary body-hugging shape and draft free closure, and at the same time retain most of the endearing quilt features we've come to love.


Conservatively defined as 15°F . The loft is a minimum of 2.75" 

Advanced baffle layout. Together with our carefully calculated fill volumes, the tapered and individually optimized baffles help to eliminate migrating down and cold spots. Along with loft, these are crucial design components for a cold weather quilt.

Differential cut. The outside of the quilt is built with a proportionally larger girth and length. This keeps the insulation fully lofted even when attacked by a restless sleeper.

No-strap design. The 3D Quilt is form cut to encourage hassle free wrap, while the full zipper closure offers a last resort barrier on the coldest of nights. These semi-quilts will still adapt to the typical quilt blanket mode, however not in the same sprawling manner as the more traditional Arc UL, found here.

Goose down. We use only high quality 900 fill power goose down, in plain untreated or Hyper-Dry to resist loft-killing moisture. Our batches are certified ethically sourced/harvested and can be tracked upon request.

Draft collar with left and right sided cord controls. The cozy, overstuffed neck collar holds the warmth inside and keeps tight cords away from skin.

Dual draft tubes along the zipper. These baffles stops drafts along the zipper and allow sleeping with the zippered side facing up or down.

Size specific zipper length. We install a zipper with a length that is balanced to the size of the quilt, ranging from 48" to 68".


The length is given in inches from the inside foot to the top of the neck baffle When cinched shut around a user's shoulders the length will shrink by several inches. Optimized for colder seasons, this quilt should be able to reach to the top of the user's head in open mode.

The width of 60" is the gold standard mummy circumference that fits most.

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.

Down Overfill

Adding overfill can prolong the life of the down, help maintain loft during moist conditions, boost the temperature rating by a small amount and keep the down volume from shifting. For most quilts/bags the overfill amount ranges from 45-65 grams of extra down
