The Arc UL quilt is a specialists' tool, with lowest weight and bulk as the guiding design parameters. Features, functions and materials are all dialed in to meet the UltraLight goal.
Fabrics and Hardware
The Arc UL is built with the lightest fabrics we have been able to source. When using materials as thin as the unique Membrane .66 and Quantum equivalents, some compromise in durability and longevity must be anticipated. Generally though, in the hands of experienced users, normal life spans can be achieved with proper care.
Besides the custom sourced shell and liner materials, we also consider shock cords, buckles, snaps and other notions as specific targets for UL optimization, further shaving grams.
The Arc UL is available from a 30°F summer style quilt all the way down to 5°, in steps geared to fit the most useful seasonal applications. By far the most popular all-round rating is the do-it-all 20°.
A six step measure of the inside useful length in 5" increments is used parallel to the subjective and sometimes confusing Small to X-Long moniker. Using this system you can choose how far up the quilt reaches when lying on your back. Reaching just the chin level is the absolute shortest anyone should go, and then only on quilts for the warmer seasons. Forehead is the best compromise of low weight - efficient coverage. As always, it is prudent to size up if in doubt. If just a little too short one tends to compress the foot area insulation to the detriment of cold feet.
Furthermore the shoulder and foot area widths can be customized for individual needs and sizing. Typically a 2 season quilt can be built a little narrower than a winter oriented set-up. If you're new to backcountry quilts, experiment at home with a blanket before committing to a sizing setup.
Foot End Design
The Arc UL quilts are offered in two foot box configurations, also in the menu below. The traditional Arc design is a 24"-28" permanently closed section finished with a round bottom piece sewn in place. In other words, a sight familiar from high-end mummy bags.
The Vector foot end is a modular concept that allow the user to switch from closed to blanket style open foot area in a few simple steps. This option, while very adaptable to changing conditions, lack a little in thermal efficiency compared to the regular Arc. It also adds a small amount of weight, for those who count every gram. A page with a few pics detailing the foot box options is here.
