Abstract
An outdoor item such as a sleeping bag, jacket, hat or blanket with one or more ventilation/temperature adjustment openings. Each ventilation/temperature adjustment opening includes, in one embodiment, a mechanism that serves to either form an opening in one or both of the outer layer, and the inner layer of the outdoor item. In another embodiment, the one or more ventilation/temperature adjustment mechanism includes an air bladder which, when inflated, serves to push aside any insulation adjacent the deflated air bladder while in both embodiments, allowing the outdoor item to vent better, thereby cooling an occupant using or wearing the outdoor item thereby offering temperature regulation.
