Designed for Swiftwater Rescue Technicians Designed in cooperation with a large Southern California fire department’s aviation unit and USAR teams to meet their requirements for an ergonomic rescue swimmer harness, our Swiftwater Rescue Technician (SRT) Harness combines vertical lift capability while being worn underneath a PFD. Extensive field testing by actual SRTs, USAR specialists and lifeguards resulted in this unique harness design. The harness includes a front waist D-ring for rappels and a rear waist D-ring for travel restraint inside a helicopter. The harness is manufactured using polyester web to minimize strength loss when wet and to allow for quicker drying. Stainless steel hardware reduces corrosion from frequent exposure to water.
