A sleeping bag has an elongate shell defining a longitudinal axis and an inner volume sized and shaped to receive a user therein. The shell has a pair of fastener-less arm ports. Each of the arm ports is selectively moveable from a closed port position to an opened port position. Each of the ports has an inner panel and an outer panel. The inner panel is positioned in overlapping face-to-face engagement with the outer panel in the closed port position such that the inner and outer panels are generally in the same plane as the overlying portion. The outer panel is spaced from the inner panel in the opened port position to define a passage for allowing the user to extend their arm through the respective port.
