The Arc Alpinist zippered quilt, or hoodless mummy, is very adaptable to a broad range of situations, conditions and seasons.

Design

The layout of the Arc Alpinist is more form fitting than the regular Arc Quilts, helping to eliminate air pockets and extra bulk, but also do not allow the quilt in comforter mode to be quite as 'open' and sprawling.

The Arc Alpinist can be used as a hoodless mummy bag in a number of ways: With the zipper facing down and closed for a snug, draft free setup; or with the zipper up in similar fashion to the Nunatak Alpinist center zip mummy bag for effective venting and ease of getting in and out.

Alternately, with the zipper fully open and disengaged, the Arc Alpinist enter full quilt comforter mode, merely draped over the user, for maximum coverage and temperature control. The foot section remains closed in all configurations.

Features

The YKK #3 48" long zipper is backed by two down filled draft tubes and protected by a stout, fabric saving gusset when fully open. The top opening is draw cord controlled and includes an effective down filled collar.

Except for the 30°, all temperature ratings are built stock with a differential cut relationship between shell and liner. This creates a slightly smaller liner, greatly assisting in proper lofting of the down and preventing cold spots. For the 20° and 15° this diff cut is 2", for the 5° it is 4".

Available for the Arc Alpinist we have literally a staggering amount of shell fabric choices. Please consult the Fabric Info page for detailed description. Basically there's 3 distinct groups:

*The UL (UltraLight) shells in 0.66 and 0.8 ounces per square yard. 

*The standard shells in 1.0 oz/yd, plus a couple of nice camo fabrics.

*The two advanced waterproof/breathable options. Take note that a significant increase in final cost is associated with these.

Custom features including sizing and weight saving options. 

Product Options
  
  Quantity:
Temperature Rating
The all time most popular choice is the versatile 20°F.
30° is considered a 2 season rating, while 5° qualifies for light 4 season use.
Inside Length
The useable length measured from inside the footbox to the top hem, without compromising the insulation loft. For example, if you're 6' tall and want the quilt to reach near the top of your head, choose 70".
Width in Open Quilt Mode
On this zippered quilt the 54" width is very snug, and only recommended for slight frames!
Foot Box Circumference
Shell Fabric

Please go to the Fabric Page for help choosing the shell material.

Liner Fabric
Down Type
Choosing Hyper-Dry moisture resistant down will help combat the effects of perspiration, misting tents and damp air. Nunatak products made with Hyper-Dry down will have a slight increase in bulk over those made with regular down. In some instances they may contain an additional 5% of fill weight.
Down Overfill
Cold sleeper? Consider adding a few ounces of extra fluff.
Gamut Climashield Over-quilt Compatability
This mod makes a future over-quilt application as effective as possible. It adds snap buttons in the places needed, plus stores a record of your product's finished measurements and attachment points.
