    The Mustang Survival MD3188 Inflatable Work Vest has a comfortable and low-profile fit and offers enhanced mobility with reduced heat stress, allowing crews and professionals to work more efficiently throughout the day. Its 35 lb buoyancy rating also means they'll have the added safety of extra flotation when they need it. Ideal for constant wear situations, hot, humid conditions and high mobility requirements

    Mustang Inflatable Vests with Hydrostatic Inflator Technology (HIT) offer reliable inflation in a low maintenance design that will only inflate automatically when submerged in 4 or more inches of water, and will not inadvertently due to rain, spray or humidity. This technology is exclusive to Mustang Survival.

    * Mustang Hydrostatic Inflator Technology (HIT) PFDs are Maintenance-Free for 5 years from the date of manufacture or until the vest is inflated, while standard, water soluble, bobbin style inflators should be replaced every year.

    • Notes:
      • Use only Mustang Survival Rearm kits. Use of other Rearm kits may result in improper operation or failure to operate and will void the product's warranty
      • Modification of a Life Vest will void its Warranty and void its Coast Guard Approval
        • Modifying a PFD, such as (permanently) adding additional body strap webbing, voids the device's approval, no matter who does the modification. However, for a person with a chest size over 130 cm (52 inches), using an adult universal PFD with a clip-on body strap extension does not void the approval. If a PFD manufacture wishes to provide the body strap extension, we recommend that it be provided with a PFD pamphlet and a caution that the PFD with the extension be tested by the individual user
    • Mustang Survival products are warranted to be free from defects in materials and workmanship for a period of one year from the date of purchase
