Abstract
A sleeping bag device has a heat-retaining bag which defines an inner chamber for accommodating the user's body and having a head opening serving as an entrance/exit. The device also has an elastic member or members which compress the warmth-retaining bag in such a manner as to reduce the cross-sectional area of the inner chamber, thus allowing the bag to closely fit around the user's body.
