Two levels of warmth offering true cold weather capacity in an advanced backcountry quilt design.
Warning: Last items in stock!
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.
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 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.
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 protect 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. 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 cozy, 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 quilts are designed for. When purchasing the 3D Quilt there's an option for selecting our premium Down Balaclava for 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 to 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. 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 10 or 11 shoes.
