Back to Nunatak Sleeping Bags


This concept provides the frequently requested link between our quilts and a regular mummy type bag. It was originally conceived by Glen van Peski of Gossamer Gear.

The Catabatic SL is a regular mummy style sleeping bag, with the underside insulation replaced by a single ultralight layer of fabric. This accomplishes a number of things. First bulk and weight is greatly reduced, always a quest in our designs.

Furthermore, the need for a zipper as a mean of ventilation is eliminated: To cool off, one simply rotates the bag to expose portions of the permeable bottom fabric. Because of the added hood this may work better with the regular Catabatic. Without the zipper we again shave off several ounces, and reduce the risk of mechanical failures.

Unlike our quilts, this bag is bug proof, a concern for some of our customers who favor tarps over tents.

The Catabatic SL is also available without the hood, see here.
