Down Hammock

Abstract

An outer layer of fabric may be disposed under an inner layer of fabric with insulation disposed between the outer and inner layers of fabric. The insulation and fabric may be sewn in a baffling pattern to minimize insulation clumping and to maximize the retention of heat within the hammock. The disclosed embodiments may provide an insulated sleeping hammock suitable for backpacking and other forms of camping. Unique folding seam patterns provide strong attachment end points such that the hammock may be securely fastened to a pair of poles or trees. The unique folding seam patterns provide arm rests for a user as well as a strong anchor point for a zipper or hook and loop attachment system along the longitudinal edges of the hammock, allowing a user to close the sides for added warmth and protection from the elements.
