Morphology

air + jacket

The meaning is directly derivable from combining 'air' (gas/filled with air) and 'jacket' (an outer garment): a jacket that contains air to provide buoyancy. This follows common composition patterns (cf. 'air mattress') and would be understandable to a B1 learner who knows both constituents.

Etymology

Air jacket comes from the simple idea of a jacket filled with air that helps you float in water. That's why the name means 'a life jacket' made to 'keep a person afloat'.
