A compact zipper-less sleeping bag in 28°F or 18°F.
In the length options below it can be configured form very short half bag to a full length hood-less and zipper-less sleeping bag
As a half bag, the Akula is designed be used with our Kobuk/Skaha line of mountain parkas creating 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 in half bag mode. 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. We leave our arms in the sleeves and simply stick the hands inside the Akula or in the parka pockets.
Choosing a length option roomy enough for full body coverage the Akula becomes a light, compact and fail-safe sleeping bag for consistently cold conditions. Take note that venting during use in warmer temperatures is difficult due to the zipper-less design.
Another option for fine tuning the Akula Down is an extended single layer fabric 'sleeve' permanently attached to the top edge of the insulated part. Long enough to cover one's head with a scalloped cut that makes the front lower than the back. Two drawstrings: one at the top of the half bag, operated from the inside, and another controlling the top of the sleeve. See here for pics
