A hot new idea is making it easier to stay warm and whip up meals on the trails, or at home. The Clasp Burner is a compact gas burner that is smartly designed to be put together quickly with only a handful of lightweight components. Flames form fast with the butane gas. Pack it up and it’s ready to go, making the Clasp Burner one of the most portable cooktops out there. S’mores, anyone?
