USGI LPU-41/P HESP Inflatable (Mae West) Life Preserver - Used

USGI LPU-41/P HESP Inflatable (Mae West) Life Preserver - Used

The LPU-41/P HESP (Helicopter Egress System for Passengers) Life Preserver is a highly specialized, mission-critical flotation vest engineered explicitly for the United States Marine Corps and U.S. Navy. Designed to be worn by helicopter passengers flying in full combat gear, it was also selected by the USMC for deployment inside Assault Amphibious Vehicles (AAVs) to guarantee instantaneous waterborne egress capabilities if a vehicle or aircraft breaches the water.

Manufactured by industry leader Switlik Survival Products under Mfg Part # S-2531-1, this low-profile, yoke-style carrier is built to integrate flawlessly directly over heavy body armor systems, including the Modular Tactical Vest (MTV) and Outer Tactical Vest (OTV), without adding restrictive torso bulk or interfering with tactical mobility. Featuring an advanced dual-cell architecture, the vest expands to deliver an immense 65 lbs of buoyant force, ensuring a fully combat-loaded soldier is rapidly driven to the surface and kept face-up.

In Used military surplus condition, these units are sold strictly as collectible, display, or training items. Because they are sourced out of active military turn-ins, they may have bypassed formal recertification dates, show signs of field wear (staining, fading, or unit markings), or be missing internal consumable components like CO2 cylinders.
