An advanced 2 season backcountry quilt design with two insulation levels.
This product is no longer 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 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.
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.
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.
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.
The pictures below are the same as used for the warmer 15°F/5°F 3D - the appearance and features are similar between the two.
