Part# 13-24036
MFR Model# S-9470-1


The UA-80 Evolution vest is the first of its kind. It’s the first FAA approved commercially available underarm constant wear life vest, utilizing SWITLIKS signature underarm flotation.

When inflated, SWITLIK’s signature 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.

Like all signature SWITLIK products, every inch of the Evolution vest was designed for a purpose. The UA-80 Evolution is FAA approved to TSO-c13G.
