A compact waist high sleeping bag in 35° or 20° to be used with our mountain parkas as a complete system for 3 season or high altitude bivouacs.

For more than half a century the climbers of the European Alps have embraced this concept for one or two night forays into the hills. Nunatak has given new life to idea of the historic 'Elephant's Foot' with the Akula. 

High tech fabrics, 900FP down and Nunatak's supreme craftsmanship makes the Akula superior to the crude chopped off sleeping bags of the old mountaineers.

This seemingly odd sleep system combining a short bag with a full strength down parka is so warm and versatile that it has become the Nunatak staff's preferred 3-4 season overnight climbing setup. With the 20° Akula it matches a 15 to 20 degree mummy bag in warmth, but wearing the parka full time makes all camp chores a less numbing experience.

We leave our arms in the sleeves and simply stick the hands inside the Akula or in the parka pockets.
For sitting or limited space no other system works better, save for maybe the Raku, another Nunatak exclusive.

4 choices in length and two footbox sizes, besides the full suite of Nunatak technical fabrics, round off the custom features.

Akula

Given the kind of backcountry stuff I do now (mostly backpacking with occasionally an easy alpine ascent) I have long wanted a half bag since I always carry a puffy jacket. The Akula 20 deg was overkill so I asked if they could give me a 35, which they agreed to, reducing the price accordingly. They were most accommodating and efficient and delivered it on time. It is excellent and exactly fits my needs and compresses to not much more than the size of a grapefruit. I've used it 3 times now, the latest being at 5400 feet. I'd strongly recommend it if you have similar needs.

    Inside length
    The Akula works best if the top reaches at least to the belly level. For sitting use add a size.
    Footbox Size
    The 38" footbox fit most normal sized feet without footwear.
    Shell Fabric

    Please go to the Fabric Page for help choosing the shell material.

    Liner Fabric
    Down Type
    Choosing Hyper-Dry moisture resistant down will help combat the effects of perspiration, misting tents and damp air. Nunatak products made with Hyper-Dry down will have a slight increase in bulk over those made with regular down. In some instances they may contain an additional 5% of fill weight.
    Down Overfill
    Cold sleeper? Consider adding a few ounces of extra fluff.
