Back to Nunatak Sleeping Bags

A compact waist high sleeping bag to be used with our Torre mountain parka as a complete system for winter 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 Elephants Foot with the Akula.

High tech fabrics paired with fine down fill and Nunatak's supreme craftsmanship makes the Akula far 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 winter camping setup for use here in the North Cascades. It matches a 0 to 10 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 cramped bivvy no other system works better, save for the Raku, another Nunatak exclusive
