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

For the cold sleeper wishing to combat drafts effectively the 3D in this configuration provides solid 2 season mountain use. 

Features:

Two levels of insulation: Conservatively rated at 35°F and 25°F.  Fill volumes for either level are detailed in the charts below, and offer further insight into whether these quilts will meet your needs. 

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 (25°F only). 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.

Enhanced moisture protection in areas of exposure: Optional waterproof/breathable fabrics protects the upper quilt where moist exhalations can wet out the insulation; as well as the foot section, an area often rubbing with damp shelter walls. Also available is a full waterproof/breathable shell option. This performance fabric adds little additional weight to a finished 3D Quilt.

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 cosy, overstuffed neck collar holds the warmth inside and keeps tight cords away from skin.

Optional lining of extra durable fabric in the fully enclosed footbox. This area typically sees the most wear, whether from calloused feet or the storing and drying of footwear. Substituting the standard liner for a 20D material gives this area an edge in long term durability. Expect a minor weight increase.

Dual draft tubes along the zipper. These optional baffles are for users who anticipate sleeping with the zippered side anywhere but downwards.

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".

Sizing:

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 over the top of the user's head in open mode.

The standard open quilt-mode width of minimum 62" is measured unstretched. It is dimensioned to offer adequate room for even large frames when the 3D Quilt is zipped shut.

2 footbox sizes are available. The 40" is good for most folks up to size 10 or 11 shoes.

Breathable 10D Taffeta, Black.
 
Inside Footbox Liner upgrade
Adding the burlier 20D liner fabric option to the foot area gives this high wear area a little more durability for the long term.

Also useful if storing and drying items inside the quilt.

Yes, please include 20d durable foot liner material
 
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. A 5% increase in fill weight also occur.

Differential Cut
The standard differentially cut design creates a bigger shell compared to the liner. This allows the insulation to achieve full loft and helps eliminate cold spots.
 
Yes. Please!
 
Integrated Neck Draft Collar with Cord Channel
This standard feature creates an insulated collar at the top of the quilt, aiding in draft control and keeps the stiff shock cord away from the skin.
 
Yes, Please!
 
Zipper
The 3D Quilt is useful in regular quilt 'open' mode, with the zipper completely undone. On the coldest nights the zipper can be applied as a last defense.
The zipper is primarily designed to be under the user, but with the optional draft tubes along the sides of the zipper, it can also face up or sideways.

 
#3 YKK Coil. One way. Inside/outside slider pull. Lightest option.
 
 
#5 YKK Coil. Two way. Inside/outside slider pull. More durable option.
 
Draft Tubes Along Zipper
Choose draft tubes if you want to use the quilt with the zipper facing up, or if you expose the underside when turning.
 
No Thanks!
 
 
Dual Draft Tubes Along Zipper
 
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. Expect a weight increase ranging from one to six ounces depending on the product, the size and the rating.

Stuff Sack
Our stuff sacks are pretty dope, but current weight saving trends in ultralight circles eschews this once crucial item. So, opt out and save $ while also being very current.
