The Gamut quilt does a lot things really well. But first a couple of comments regarding synthetic insulation.

Synthetic Climashield APEX Insulation

Nunatak has always been a manufacturer of down equipment. When we started in 1999 synthetic insulation was a joke. Literally. Short life span, especially if laundered, very bulky, not particularly light.

When Climashield APEX was introduced a number of years ago, we started watching. The specs were agreeable and feedback from the field was positive. And the stuff seemed to last more than one season. 

Climashield APEX is likely is the lightest and most thermally efficient continuous filament insulation on the market today. It's nice and light, besides being the most compressible synthetic we have seen. You can wash it, even. Or so they say.

The Gamut

We spent the summer developing and testing the Gamut, and found it to be a great stand alone product. But even more so, the Gamut is the perfect companion piece to a down based quilt or mummy. More about this in a bit.

Basic features of the Gamut synthetic quilt

3 temperature ratings based on pre-cut and stabilized Climashield APEX sheets: 35° - 42°- 50°. 

Ultralight fabrics: Shell of either Pertex Quantum 0.8 oz/yd or Membrane 0.66 oz/yd. Liner material always Membrane. These are fabrics with very effective vapor transfer and a soft, pleasant feel. 

The Gamut exhibit proven quilt design with critical improvements: Blanket style layout with a convertible footbox (flat/open or closed/snug), drawcord end closures and our draft stopping strap system. Form cut fit and long lasting built quality rounds off the features carried over from our line of premium down quilts.

We wanted to solve a couple of other issues. The convertible footbox needed to be able to close up in a thermally effective manner. The basic idea of a stuff-sack style drawcord opening, while appealingly simple and foolproof, had to be improved. We re-cut the shape of the foot end of the quilt in order to bring the closure down and under the feet. This is a design change well needed in openable footbox synthetic quilts, creating a very tight and snug feel. 

The drawcord channels at the top and bottom behave differently due to the un-quilted construction with no baffle stitching. On our down quilts these channels are moved in from the ends to create insulated areas at the head and foot interface. This method will not work on synthetic covers. The solution is an internal channel of precise circumference, but changing in size with the different insulation values available.

When to choose Synthetic Insulation

As a stand alone moisture resistant, down-shifting immune quilt the Gamut surprised us. It felt warm and cozy, and sound sleep was ensured knowing that damp tent walls, or heavy dew, did little to diminish the loft. Quite comforting, in fact. 

The secondary use of the Gamut is as a booster over-quilt on top of down mummies and quilts. This solution is equally effective and can save the substantial investment in a dedicated winter bag. With the continuous sheet style Climashield insulation there's always a cover over bald spots from shifting down in the main bag. Again, dampness from external sources are typically only affecting the synthetic, while the below the down remain protected. And condensing body moisture that are settling in the steep temperature gradient of the outer layers are also away from the down. This quality is especially valuable in winter conditions.

Compatibility and Sizing

Nunatak down quilts and the Gamut are designed to join effectively with correct sizing for efficient coverage, and also minimizing the strap and snap clutter.

There's an option in the configuration menu of new down quilts to install the needed hardware for future Gamut over-quilt application. Backwards compatibility is possible by sending your old Nunatak quilt to us for the necessary mods when purchasing a Gamut. 

The Gamut will also fit over just about any existing quilt or mummy. It is however important to size it right. Call or email if in doubt.

The Gamut size run is highly customizable. Length, width and foot area are offered in many sizes and an untold number of combinations to fit all frames and applications.

Refills!

Climashield, being a synthetic insulation, will likely not last as long as a quality down fill. After extended use, involving several laundry cycles,  it could become 'flat' with significant loss of loft. If this happens, the Gamut design enables us to easily replace the fill at the Nunatak shop. Built for the long haul!

The 42° Gamut is here over-quilting an Arc Alp 30°. The combined temperature rating is in the teens.

Nunatak down quilts snap to the Gamut, while still allowing the use of standard under-body straps. 

The openable foot box is designed with a domed cut that moves the cinch center under the feet when tightened.

Great quilt!

I ordered a 42°, 85" length, 57" width quilt back in November 2016 and couldn't be happier! I am able to pack it down very small in a compression sack and it weighs very little. I recently used this with a 40° bag on a backpacking trip where temps at night were about 30° and I was very comfortable. I look forward to warmer months when I can use just this quilt on my trips!! Great product, company answered all my questions when I called prior to the order, kept me informed as the item was being made, and I look forward to ordering more items in the very near future!!
