The Arc Lite is a versatile backcountry quilt . It's a box baffled 20° quilt with a closed traditional footbox, a draw cord at the top hem and a set of straps to pass under the body. The down is premium white goose down coupled with quality fabrics. We sew these with the same attention to detail as all our products.

What makes the Arc Lite a good choice? 

Cost. The Arc Lite is affordable. $250 base price in all sizes and always free US domestic shipping. If you are outside the US and want to purchase the Arc Lite it will add a flat cost of $25 to the price. Please go here for international shipping.

Many sizes. 6 lengths in 5" increments; plus a standard 52" width for good coverage.

The down fill is rated at 850 FP.  A solid high loft performer, the 850 class of down is durable, long lasting and affordable. For the Arc Lite we offer the fill in either regular quality or with a Hyper-Dry moisture resistant treatment.

Simple, proven design. Featured is a cord channel with shock cord at the top neck snap closure; and a closed foot area with an ergonomic cut and efficient cozy space.

Quality shell fabrics in five colors: Silvery black, bright blue, carmine red, sage green and royal purple ripstop nylon, weighing 1 ounce per square yard. A tried and tested material with good qualities, balancing low weight with an edge in durability not seen in the super ultralight materials.

Super soft inside fabric. Specifically designed for sleeping bags, our matte black taffeta wears well and provides a non-sweaty flat material comfortable even against naked skin.

Option for overfill. Dial in the fill volume for your needs. Cold sleeper? A few ounces of extra down will boost the temperature rating by several degrees.


The fill volume in the Arc Lite is generous. While this makes them slightly heavier than many competitors, there are several good reasons to begin with a properly filled sleeping bag/quilt.

The number one reason is the issue of displacing down due to the user tossing and turning during a nights sleep. In extreme cases such shifting can leave bare spots and lower the effectiveness of the quilt. Overstuffed chambers helps to a large degree. Judiciuos fluffing and re-depositing of down is a ritual most experienced users accept, but as the Arc Lite is an attractive first-timers quilt it attempts to eliminate this easy to forget procedure.

With more down than is technically needed to meet the target rating, the Arc Lite is likely warmer than specified. Again, this helps a beginner backpacker who may not be aware of the many little tricks needed to use ultralight equipment to their advantage. 

Finally, like all things, goose down degrade over time, especially if mistreated or cycled through many user days. With overfilled box baffles this future loss of loft is effectively anticipated. 

The down fill weights for all sizes are listed in the blue table below. 

In the menu options one can choose even more down overfill in one ounce steps.

The stuffed size of a medium is 15" long and a circumference of 20"


Superbly crafted

You won't get better quality for your dollar here. Expert craftsmanship and great materials make this the best value quilt on the market. Nunatak continues to deliver the best!
