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.

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


Versatile 25°F comfort rating: Loft of about 2.10". Fill volumes for popular sizes are detailed in the charts below, and offer further insight into whether this quilt 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.

Goose down. We use only high quality 900 fill power goose down. 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".


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 width is offered in three sizes. 60" is the gold standard mummy circumference that fits most. Very small frames will benefit from the 54" to entrap less dead air. Folks desiring lots of wiggle room can select the 66". 

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

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
