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.

We make them in 4 temperature ratings, conservatively stated as 35°F, 25°F, 15°F and 5°F.  On this page you can select the sizing and features pertaining to the 15 and 5 degree versions.

The 3D was designed in a response to the luke warm reviews of the generic cold weather quilt. 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.

Proper experience and precautions are needed for successful applications in the conditions meant for these quilts. 


Two levels of insulation: Conservatively defined as 15°F or 5°F. The loft is a minimum of 2.75" and 3.25".  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. 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.

Hyper-Dry goose down. We use only high quality 900 fill power white goose down, treated to resist loft-killing moisture. Our batches are certified ethically sourced/harvested.

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.

Premium Down Balaclava available at 50% cost savings. Night time heat loss from the head is not to be underestimated. Even the hood on your ultralight down jacket may be inadequate in the conditions these quilt are designed for. When purchasing the 3D Quilt there's an option for selecting our premium Down Balaclava for less than half the cost found elsewhere on this site.

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".


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.
