HIT™ Automatic Inflatable Life Jackets with Harness

When you're offshore, shorthanded, or caught in conditions that deteriorate faster than expected, your life jacket needs to be the one piece of safety equipment you never have to think about. It needs to be comfortable enough that you actually wear it all day, reliable enough that it deploys when you need it and not before, and engineered to a standard that holds up through years of saltwater exposure without constant maintenance intervention. The Mustang Survival HIT™ Automatic Inflatable Life Jacket with Harness is built to exactly that standard — combining Mustang's exclusive Hydrostatic Inflator Technology with a 5-year maintenance-free service interval, an integrated sailing harness, SOLAS-grade reflective tape, and the comfort features that make the difference between a PFD that gets worn and one that stays below.

This is not a casual recreational life jacket. The Mustang HIT™ is engineered for serious offshore sailors, bluewater passage makers, coastal cruisers, and anyone who spends meaningful time on the water in conditions where automatic inflation reliability and harness integration are genuine requirements — not marketing features.

Hydrostatic Inflator Technology (HIT) — The Most Reliable Automatic Inflation System Available.
The fundamental challenge of automatic inflatable PFD design is a paradox: the device must fire reliably when the wearer enters the water in an emergency, but must not fire prematurely from rain, spray, perspiration, humidity, or the routine wet conditions of sailing and boating. Conventional dissolving-pill or bobbin-based automatic inflation systems solve this imperfectly — the water-soluble element can be degraded by humidity, spray, or condensation over time, leading to either premature inflation or, worse, a failure to inflate when actually needed.

Mustang's Hydrostatic Inflator Technology solves this problem with a fundamentally different mechanism. The HIT inflator responds to water pressure — not water contact. It activates only when submerged to a depth generating a specific hydrostatic pressure equivalent to approximately 4 inches of water. This means:

• Rain does not trigger it. No matter how heavy the downpour, rain impacting the surface of the PFD does not generate the sustained hydrostatic pressure required for activation.
• Spray does not trigger it. Breaking waves over the bow, green water in the cockpit, and spray from any source do not produce the required submersion pressure.
• Humidity and condensation do not trigger it. The pressure-based mechanism is completely immune to moisture in the air or on the surface of the device.
• Submersion activates it immediately. When the wearer enters the water and the PFD reaches the required depth — which happens within seconds of a man-overboard event — the hydrostatic pressure triggers immediate, reliable inflation without any action required from the wearer.

This is the most operationally reliable automatic inflation mechanism available in recreational and professional PFD design, and it is exclusively available in North America from Mustang Survival. For offshore sailors and serious boaters who demand a PFD that performs with absolute reliability, HIT technology is the definitive standard.

5-Year Maintenance-Free Service Interval — The Operational Advantage That Sets HIT Apart.
Conventional automatic inflatable PFDs require annual inspection and replacement of the arming mechanism — the water-soluble bobbin or pill that triggers inflation. This annual service requirement is not optional; it is a manufacturer and USCG requirement for maintaining the device in an airworthy, ready-to-deploy condition. Miss a service interval and you may be wearing a PFD that will not inflate when you need it.

The Mustang HIT™ changes this calculus entirely. Because the hydrostatic inflator mechanism is sealed, pressure-actuated, and not susceptible to humidity or moisture degradation, it carries a 5-year maintenance-free service interval from the date of manufacture — or until the device is inflated, whichever comes first. For the first five years of the device's service life, no annual arming mechanism replacement is required. This is not a minor convenience — it is a meaningful reduction in the ongoing cost and administrative burden of PFD ownership, and it removes the most common failure mode of conventional automatic PFDs: the arming mechanism that was due for service but never got it.

After 5 years from manufacture date or after any inflation event, the device requires service per Mustang Survival's guidelines. Always verify the manufacture date and service status before going offshore.

Integrated Sailing Harness — Tether-Ready for Offshore Use.
The HIT™ is not merely a PFD with a harness accessory — the harness is an integral engineered component of the system, designed to meet the load requirements of offshore jackline tethering. For bluewater cruisers, offshore racers, and coastal sailors who practice proper jackline and tether protocols, the integrated harness provides the structural attachment points needed to stay connected to the vessel in the event of a knockdown, broach, or unexpected MOB situation. A tether connected to the harness keeps you on the boat; the PFD keeps you afloat if you go over. Together, they constitute a complete offshore personal safety system.

SecureZip™ Closure — Engineered for High-Energy Activities.
Inflatable PFDs must balance two competing requirements at the closure: the jacket must stay securely closed during vigorous activity to maintain its low-profile, non-restrictive fit, but the closure must open immediately and completely when the bladder inflates — because a closure that resists the inflating bladder can compromise buoyancy and wearer positioning. Mustang's patented SecureZip™ closure system solves both requirements simultaneously. The closure holds the PFD securely closed through the physical demands of offshore sailing, racing maneuvers, and active deck work, then opens effortlessly and completely as the bladder inflates, allowing the full buoyancy volume to deploy without restriction.

Neoprene Comfort Collar — The Detail That Determines Whether It Gets Worn.
The single most common reason sailors remove their PFDs during extended passages is collar discomfort — the chafing of a hard or textured collar against the neck during hours of continuous wear. Mustang addresses this directly with a soft neoprene collar that eliminates the primary chafe point, making the HIT™ genuinely comfortable for all-day, all-passage wear. A PFD that stays on provides protection; one that comes off in deteriorating conditions does not.

SOLAS Reflective Tape — Search-and-Rescue Grade Visibility.
The inflation cell of the HIT™ is equipped with SOLAS-grade reflective tape — the same reflective specification required on commercial life-saving appliances by the International Convention for the Safety of Life at Sea. SOLAS reflective tape is engineered to return a significantly stronger signal to a search light, spotlight, or helicopter searchlight than standard recreational-grade reflective material. In a nighttime man-overboard search, this distinction can be the difference between being found and not being found. SOLAS reflective tape on a recreational inflatable PFD is a premium specification that reflects (literally) the seriousness with which Mustang Survival approaches offshore safety.

Manual Inflation Handle — Always Available as a Backup.
In addition to automatic hydrostatic inflation, the HIT™ includes a manual inflation handle that allows the wearer to deploy the bladder at any time by pulling the handle — whether the automatic mechanism has not yet activated, the wearer prefers manual control, or as an added layer of redundancy. The handle is positioned for easy one-handed access in the water and is secured to prevent inadvertent deployment during normal use.

Oral Inflation Backup Tube.
A dedicated oral inflation tube provides a third inflation pathway — allowing the wearer to top up buoyancy by breath after CO2 inflation, or to inflate the bladder manually in the unlikely event that both the automatic and pull-handle systems are unavailable. This triple-redundancy inflation system — hydrostatic automatic, manual pull handle, oral tube — represents the most complete inflation reliability architecture available in recreational PFD design.

Status Indicator Window — Instant Readiness Confirmation.
A clear indicator window provides immediate visual confirmation of the PFD's armed and ready status without opening the cover or disassembling the device. Green visible in the window means the device is properly armed and ready to deploy. This feature is particularly valuable for a PFD with a 5-year service interval — a quick window check before each offshore passage confirms status at a glance.

Zippered Pocket — Practical Storage for Safety Essentials.
An integrated zippered pocket provides secure storage for small safety items — a personal strobe, folding knife, signal mirror, or other compact emergency gear — keeping critical items close at hand and secured against loss in the water.

Safety Whistle — Included and Ready.
A USCG-required safety whistle is included and attached to the jacket, providing the audible signaling device needed to attract attention in the water when visual signals are ineffective at short range.

Lightweight and Low-Profile — Built to Be Worn.
Despite its comprehensive feature set, the HIT™ maintains the low-profile, lightweight construction that makes it practical for all-day wear. It layers comfortably over a t-shirt in warm conditions and over mid-layer sailing gear in cooler weather, without the bulk or weight that causes sailors to remove their PFDs during long passages.
