SENTRY LPU with Hammar Hydrostatic HIT Inflator - Berry Compliant
Model: MD1401GB / SKU: 062533026902
The Sentry LPU combines proven elements of Mustang Survival’s Compact Tactical LP and RATIS™ SOF LPU to balance compactness, weight, durability and serviceability. Equipped with a Hammar Hydrostatic HIT Inflator, it delivers 40 lbf (180 N) of buoyancy with self-righting capability while preserving critical equipment space on the chest.
Size: Universal
Color: Black
Description
Positioning the inflator behind the head distributes weight evenly across the shoulders and reduces the side-to-side imbalance associated with lobe-mounted inflation systems. A flexible 10-thou film bladder allows the packed LPU to conform comfortably to the wearer while meeting the same puncture-resistance requirements as a nylon bladder. The abrasion-resistant 500D cover withstands demanding operational environments.
The inflation system uses existing rearm kits for easier integration with current equipment inventories. Integrated 3/4-inch buckles allow direct mounting to a carrier, while the included chest harness supports independent wear across different operational configurations.
A rear access pouch allows users to check the inflator’s status. Straightforward repacking also simplifies inspection and maintenance for personnel responsible for managing their own equipment.
