The 3D Apex applies everything we have developed about advanced hood-less down quilt construction, but adjusted to synthetic insulation. The result is a highly evolved, super efficient backcountry quilt with a long list of features focused on comfort and thermal efficiency.

Shaped design

The compound curved panels of the 3D Apex comes together into a naturally 'body wrapping' shape. Starting narrow at the neck before widening by the shoulders, then gradually curving in towards the foot end. This paneled design allows a quilt style underside opening with parallel edges for ease of draft sealing when needed. The sewn closed, round mummy style foot end is the lightest, warmest arrangement.

Differential cut

The outer fabric shell is sewn longer and with more transverse circumference than the inner lining to maximize the insulation value of the high loft Apex.

Weighted insulation

In the options menu low and high priority areas of the quilt can be selected with different effective temperature ratings. I.e. the foot section can be warmer than the rest; or the 'wings' wrapping under the user's torso can receive thinner insulation than the torso top.

Draft collar

The cush draft collar from the Arc UL quilt series is here too, insulated with loose fill synthetic and finished with a side controlled shock cord.

ETC draft control or full zipper closure

For the parallel sided torso underside opening one can minimize drafts while retaining classic quilt freedom with the proven ETC system pared with straps; or completely eliminate cold air intrusion by selecting a full length zipper.

Custom sizing

Correct sizing is paramount to efficient thermo regulation. We offer length adjustments in 4" increments and several different widths; plus regular and oversized foot boxes.

Use as an Over-Quilt 

Properly sized and spec'ed the 3D Apex integrates with our down sleep systems to provide a hassle free winter setup with excellent moisture fighting capabilities.

Shown here is the 30°F version with 42°F underside, in 10d grey torso and moisture resistant 7d foot section. The size is 70" L by 58" wide. The foot is the standard 40" circumference. Total weight for this version is 22.5 ounces.

Liner Material
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.

No Thanks!
Yes, please include 20d durable foot liner material
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!
Quilt Underside Closure/Draft Control

Experienced backpackers can use this form cut quilt  in regular 'open' mode, with no additional features. 

For a better defense against drafts on the coldest nights the zipper option can be selected.

Or choose the variable ETC draft control tensioner with ultralight shock cord straps.
