Back to Nunatak Sleeping Bags


A backcountry quilt for all seasons, the Arc Alpinist is roomy enough for high mountain layering, yet the unique adjustability of the Arc Concept will easily adapt to the heat of summer.

To achieve this versatility our Arc bags are constructed without zipper closures, but features an open underside outfitted with two lengths of ultralight webbing which seals the quilt around you and your pad. Tiny 3/4" center release buckles adjust the girth, for the right fit.

The temperature rating of 20 degrees Fahrenheit is perfect for the individual wishing for an all round bag. The loft is 2.5" of baffled construction, generously filled with the highest quality 800+ down.

The Arc concept is hood less, but the roomy cut on the Arc Alpinist enables you to curl up inside on nippy nights. These bags are designed to make use of the many layers of additional headwear one usually has along in the mountains. Or try one of our Down Balaclavas.
