Basic features of the Dual Gamut synthetic quilt 

The Gamut is built like an oversized classic backcountry quilt, with a sprawling blanket style top section and a mummy type permanently closed foot end.

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

Two shell fabric catagories:

#1. Either 20d Pertex Quantum for long lasting durability; or 10d ultralight and compact ripstop nylon. These are fabrics with very effective vapor transfer and a soft, pleasant feel. Super light, breathable, fast drying. Sage Green, Silvery Black, Moroccan Blue or Brick Red.

#2: Equally capable is the techy waterproof/breathable 7d Robic ripstop. At 0.74 oz/yd this weather resistant shell is an outstanding companion to the Apex insulation for really wet conditions, providing bivy-bag like performance with no weight penalty. Black, grey, light blue and olive.

Liner material is 10d or 20d, chosen with either light weight or durability in mind.

When to choose Synthetic Insulation

As a stand alone moisture resistant, down-shifting immune quilt the Dual 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 dedicated winter bags. With the continuous sheet style APEX insulation there's always a cover over bald spots from shifting down in the main bag. Again, dampness from external sources is typically only affecting the synthetic, while below the down remains protected. And condensing body moisture that settles in the steep temperature gradient of the outer layers are also away from the down. This quality is especially valuable in winter conditions.

Refills and zipper replacement!

Climashield APEX, 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!

I think we got the first of these and love it!

Having a couples quilt has really improved our comfort, sleep, and satisfaction when camping and backpacking. Sharing the warmth and snuggling like at home is great! My wife likes it even more than me. And Nunatak is awesome and all the options are wonderful to get just what you want. The Apex is great for humid and dewy conditions out east, and as an overbag below freezing to prevent condensation in your down bag inside it.
