Sleeping bag with air pockets

Abstract

A sleeping bag includes a shell defining an enclosed heat insulation space, a sleeping bag filler filling the heat insulation space, and air bags that are provided inside the heat insulation space. The heat insulation space includes a bottom portion and a non-bottom portion. The bottom portion is adapted to support the weight of a user of the sleeping bag. The air bags are positioned in the bottom portion. The air bag includes an elongated air tube, an air communication conduit, and an air plug. The air bags are spaced from one another by a predetermined interval. The sleeping bag filler fills the heat insulation space between the air bags. The air bag may further include an air bag filler that is provided inside the air tube. The air bags may be connected to form a single sealed air space.
