Built for Rescue, Adapted for Recreation: The Evolution of the Hybrid PFD

At Mustang Survival, we design gear to excel in the most extreme conditions while enhancing everyday adventures. Often, the cutting-edge technology we develop for military, coast guard, rescue personnel, and law enforcement use shapes our recreational products. The Khimera Dual Flotation PFD is a prime example of this innovation; built on the visionary platform of our MRV170 Rescue Swimmer Vest, it combines professional-grade safety with comfort and versatility for everyone on the water.

 

The MRV170: Engineering the Ultimate Rescue Swimmer Vest

Our development of the MRV170 Rescue Swimmer Vest in 2016, marked a significant innovation in personal flotation devices (PFDs). Specifically designed for rescue swimmers, the MRV170 transformed how professionals approach water rescues, combining tactical performance, mobility, and buoyancy to keep both the rescuer and the victim safe. 

A rescue swimmer is a highly trained specialist, equipped to handle high-risk situations, whose mission is to save lives wherever they're needed. Their skills often make them the first line of defense when lives hang in the balance.

Solving the Professional’s Dilemma: Hybrid Flotation & Mobility

Before we introduced the MRV170, rescue swimmers had limited options: bulky foam vests that restricted movement and vision or slim inflatable vests lacking sufficient inherent flotation. Rescue swimmers, often lowered into the water from helicopters, need both freedom of movement and precise buoyancy control to help survivors in various conditions. Recognizing these unique demands, we collaborated with professionals to design a solution. 

After two years of development, the result was the MRV170, combining foam flotation and inflatable elements into a streamlined design. The vest provides 9 pounds of inherent foam buoyancy, expandable to 26 pounds with manual CO2 inflation, ensuring rescue swimmers can operate freely without compromising on safety. Its unique hybrid design transformed a compliance-driven device into a high-performance tool, with features such as an oral inflation valve for buoyancy control, adjustable straps for a customized fit, compatibility with all harness designs and a MOLLE system for attaching gear, making it indispensable in rescue operations. 

What truly sets the MRV170 apart is its tailored design for rescue swimmers; flotation is distributed between front and back panels to prevent unwanted rotation in the water. The vest also incorporates our expertise in inflatable membrane technology, developed from military and public safety innovations.

From Professional Rescue to the Khimera Dual Flotation PFD

Streamlined Design for Recreational Users and Safety

The success of the MRV170 led us to adapt its technology for the recreational market, resulting in the Khimera Dual Flotation PFD. Using the same hybrid flotation system, the Khimera has the same professional-grade safety, reduced bulk, and lightweight over-the-head design, while eliminating the MOLLE system to simplify the vest.

We also reduced the foam (7.5 pounds of buoyancy) and bladder (13 pounds of buoyancy) to make it smaller overall and made the chassis shorter to be more compatible with kayaks. This streamlined design makes the Khimera ideal for those seeking enhanced mobility and safety on the water recreationally. As a Harmonized Level 70 buoyancy aid, the Khimera is officially approved by both Transport Canada and the U.S. Coast Guard, ensuring you are legal and protected across North American waters.
