Well, it was bound to happen. We deploy countermeasures when airlines try to weight our carry-on bags, now regulator manufacturers are responding by carefully designing regulators that are real weight defiers.

The new Apeks Flight regulator is advertised by Apeks as the worlds lightest.

They rate it as good in water temperatures down to 10C. I notice an injection molded connector system on the right side, a highly compact 1st stage and an ulratralight braided low pressure hose.
