Down Quilt

The venerable Arc Alpinist Down Quilt could very well become the most used piece of equipment in your back country arsenal.
It is roomy enough for 4 season layering, yet the unique adjustability of the quilt concept makes it ideal for use in the heat of summer. The trick to this versatility is the open bottom outfitted with two lengths of ultralight webbing which secures the quilt around you and your pad. Lightweight 3/4" center release buckles infinitely adjust the girth so you can adapt the Arc Alpinist to a wide range of temperatures.
The 20 Fahrenheit rating of the Arc Alpinist is achieved thru 2.5" of baffled construction, generously filled with the highest quality 800+ down.
The Arc concept is hood less, but a 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, or for the cold end one of our Down Balacavas.

Perfect for 3 season use in the sierra
I purchased one of these a while back to lighten my load and enable me to use a smaller pack and have a bag which was good for three season use in the sierra. When its warm just throw it on top of me, when its colder use the straps to close it up.

So far I have used it about 7-8 nights and have been very happy with it. Coldest I have used it was about 30 degrees and it kept me quite warm. I did sleep outside with it one time and could feel a breeze coming in on occasion, but it has works great in a tent or a bivy. (my intended use)
Stuffs down very small, sack I am using is about 6x12 (doesn't come with a stuff sack) and is quite light, mine is about 21.5 oz
Nunatak is a great company to deal with, and will pretty much make this to your exact specs. I purchased a medium but had them add 5" to its length.
Overall I am very happy with the purchase

Amazing, Versatile, 3-Season Bag
Like the previous reviewer, I love my Arc Alpinist. I have had it for a little over two years and three seasons. I probably have a total of forty nights in it. I have a 20 degree version with Quantum fabric and the differential cut foot box. Seperately, I got a down balaclava from down works in Santa Cruz, CA. I have used this bag on evenings with temps from the high twenties to the low forties. I find it exceptionally warm and comfortable. The top bag design allows for lots of flexibility. On cool to cold nights, I prefer to use this bag with a lightweight bivy sack from Bozeman Mountain Works to eliminate drafts. If it ever gets cold enough, I will pair the Arc Alpinist with my Nunatak SkahaPlus jacket as part of a sleep system. Nunatak's workmanship is always at the highest levels.
