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.
