The BIPRO 4 is a professional tandem pilot harness designed specifically for daily intensive use. It balances simplicity, safety, and durability while maintaining a lightweight and compact form factor at only 2.7–2.8 kg. This harness is well-suited for working tandem pilots who require robust equipment for multiple flights per day, and also for leisure tandem pilots who prioritize comfort and practical features.
The key focus of the BIPRO 4 is to serve as a reliable daily work tool, with features and construction optimized for repetitive professional use. It employs strong and abrasion-resistant materials that promise high durability. Comfort is ensured by a 3D-developed, well-supported seat coupled with V-shaped, well-padded leg pads. This design maintains a comfortable upright posture for the pilot behind the passenger, while preventing the pilot’s knees from pressing into the passenger's back, thereby enhancing comfort for both.
Safety enhancements include the pioneering use of EDELRID Triple-Lock buckles on a paraglider harness for the first time. These buckles require three deliberate sequential actions to open, significantly lowering the risk of accidental release compared to standard Click-Lock buckles. The harness incorporates an ergonomic, multi-chamber foam protector approved under EN/LTF standards that wraps around the leg pads to extend impact protection.
A notable aspect of the BIPRO 4 is its modularity and practicality. The foam protector is removable, allowing the pilot to save approximately 500 grams of weight or gain an additional 17 liters of storage under the seat depending on the day’s needs. This flexibility lets pilots tailor their setup for either enhanced protection or increased cargo volume and reduced weight.
The “Easy Fold” feature of the harness includes a defined folding section behind the protector acting like a hinge, enabling controlled folding for compact packing—an important advantage for transport and tandem operations where space is limited. Usability is further enhanced by handy extras: a versatile selfie-stick holder (mountable on either side) and a hook knife are included, supporting modern tandem operations that may involve photo/video services and safety cutting tools.
Technical Specifications
The harness is available in sizes M and L, designed respectively for pilots roughly between 155–185 cm and 175–202 cm tall, encompassing most adult pilots. Carabiner heights are 40 cm (M) and 42 cm (L), contributing to consistent hang geometry. The back pocket volumes are substantial—26 liters for M and 34 liters for L—offering ample storage space for professional tandem gear such as jackets and camera equipment. Despite its sturdy construction and foam protection, the harness remains lightweight, weighing only 2.70 kg (M) and 2.80 kg (L).
Certification-wise, the BIPRO 4 conforms to EN and NfL standards for loads up to 120 kg, ensuring compliance with European norms and German airworthiness regulations.
Materials and Durability
Materials include abrasion-resistant 25 mm polyester main straps with high strength (800 daN), 15 mm polyamide shoulder straps for dynamic load tolerance (1320 daN), and 25 mm polyester leg straps. The seat area is crafted from 210D nylon Oxford, chosen for durability balanced with weight considerations. Its outer covering uses a combination of N/P 350D melange Oxford and 210D nylon ripstop fabrics, providing robustness with some tear resistance and a modern textile look.
Scope of Delivery and Options
Included with the BIPRO 4 are the removable foam protector, an inner container equipped with a handle for reserve system integration, the selfie-stick holder, hook knife, and a helpful Getting Started booklet.
Pilots can also opt for various tandem system integration accessories, such as different spreaders (Hard Hybrid, Soft, Soft Trim) and a rescue connection line kit, allowing tailored compatibility with various tandem wings and spreader systems. The recommended reserve parachute is the Companion SQR 230. An accessory bag, the FASTPACK, is available to expedite packing post-flight.
Summary and Final Thoughts
In summary, the BIPRO 4 stands out as a purpose-built tandem pilot harness expertly balancing robustness, certified impact protection, and long-duration comfort with a relatively low weight and compact packing capability. Its innovative safety buckle system, the option to configure protection against weight and storage needs, and tailored professional accessories make it an excellent high-end choice for commercial tandem pilots who require reliable, ergonomic, and durable equipment for daily demanding use.
