Customizable Sleeping Bag Lets You Peel Back Layers to Stay Cool

It turns out the tried-and-true technique of simply unzipping a sleeping bag when it gets too hot inside wasn't good enough for some people. Someone, somewhere, demanded more options, which led to the creation of this vented bag which looks like it's endured a bear attack or two.

In addition to a long zipper running up the edge, this $120 sleeping bag has four or five additional zippers running across it allowing a finicky camper to decide how much of their body they wan't to leave exposed. The creation looks like it would function better as a straight jacket than a way to stay warm when roughing it, but it's got enough micro-fiber insulation to keep you toasty down to 20º F. More here.
