Switlik UA-80 Evolution life vest

The UA-80 Evolution vest is the first FAA approved commercially available underarm constant wear life vest, utilizing SWITLIKS underarm flotation technology (UAFT). 

When inflated, SWITLIK’s underarm flotation technology provides improved mobility, maneuverability, higher freeboard and superior water channeling when compared to traditional yoke-style bladders. It also provides auto-righting of unconscious aircrew to bring them into a stable, face-up position for unimpeded breathing.

As the flotation resides inside the vest, valuable space is added to the front for accessories. The Evolution Vest has more than twice the amount of available MOLLE loops than any previous Switlik design.
