Tuck-Stitch Construction:  Baffles are attached by folding a piece of the shell fabric and sewing through both layers to the baffle. The result is a hidden stitch less prone to snags and blow outs.
Certified Minimum Fill Power (CMFP):   All Exped down sleeping bags are filled with high-quality goose down that is certified by the International Down and Feather Laboratory to be 750 fill power or greater.
