The Inflatable SAR Vest is a compact, lightweight, over-the-head, rescue swimmer inflatable flotation device. It provides flotation characteristics normally found in large, bulky Type I flotation devices only. The Inflatable SAR Vest is self-righting, and produces a positive righting movement (face-up) with 35 lbs. of buoyancy. The vest is normally inflated manually with CO₂, or can be orally inflated with air through its oral tube.

The Inflatable SAR Vest is built from heavy duty 420 denier nylon for continuous wear, and contains a replacement bladder. This vest incorporates all currently approved changes to the Navy LPU-28A/P Rescue Swimmer Vest including the PRC-125 Modification. Includes 33 gram CO₂ cylinder.
