Five years ago, while on a particularly chilly camping trip with his father, Justin faced an age old dilemma: “How can I possibly leave the warm haven of my sleeping bag for the cold morning wilderness?” Being a natural problem-solver, Justin figured there had to be a way to stay in his warm sleeping bag and still get up and walk around. His solution: the Quad Zipper. The Quad Zipper is a new zipper technology that allows for synchronized, compartmental transformation of fabrics. The Quad Zipper simultaneously zips and unzips parallel rows of zipper tape to transform articles of clothing without adding or removing any parts. For example, the Quad Zipper transforms a sleeping bag into a walking suit, allowing the occupant to get up and walk around in their sleeping bag while maintaining the generated body heat trapped inside.
