The ADVANCE BIPRO 4 is a modern tandem pilot harness created for professionals who fly every day and leisure tandem pilots who demand the same level of comfort and safety. Weighing just 2.7 kg in size M, yet designed for intensive use, it combines robust construction, ergonomic support and clever details that make commercial tandem work noticeably simpler and more efficient.
Lightweight, Strong and Ready for Daily Work
With certification to EN 1651:2018+A1:2020 and NfL 2-565-20 for loads up to 120 kg, the BIPRO 4 is clearly positioned as a serious tool for tandem operations. Its low weight – 2.7 kg (M) and 2.8 kg (L) – is achieved without sacrificing durability: wear‑resistant outer fabrics, high‑strength webbing and a reinforced seat area are tailored to withstand countless take‑offs and landings.
Pilot height ranges of 155–185 cm (M) and 175–202 cm (L), together with optimised geometry and adjustment options, cover most tandem pilots while maintaining a balanced flying posture and precise feedback from the wing.
Safety and Comfort as Core Features
Advanced Protection Concept
The heart of the safety concept is an ergonomic multi‑chamber foam protector, EN/LTF approved and shaped to wrap around the leg pads. It delivers effective impact absorption while preserving freedom of movement. If required, the protector can be removed to gain around 17 litres of additional storage in the compartment under the seat or to save about 500 g of weight – a useful option for specific missions or travel.
Triple-Lock Security System
For the first time in a paraglider harness, ADVANCE integrates EDELRID Triple‑Lock buckles. Opening these buckles requires three deliberate, sequential actions, practically eliminating the risk of unintentional release. Combined with clearly routed straps and a tidy cockpit area, the system supports fast but controlled pre‑flight checks in a busy tandem environment.
Ergonomics for Pilot and Passenger
Comfort is ensured by well‑padded V‑shaped leg pads and a 3D‑developed seating area. The pilot sits securely and relaxed behind the passenger, without knees pressing into the passenger’s back – a crucial factor on long thermal flights or days with many rotations. The back compartment offers 26 l (M) or 34 l (L) for equipment, clothing and accessories, supporting professional logistics in the field.
Practical Details for Modern Tandem Flying
Easy Fold for Compact Packing
The distinctive Easy Fold feature behind the protector acts as a hinge when packing, allowing the harness to fold compactly and consistently. This reduces volume in the packsack, speeds up turn‑around on the landing field and makes transport to launch sites easier, especially when combined with modern fast‑packing bags.
Integrated Tools and Options
In the standard scope of delivery, the BIPRO 4 comes with protector, inner rescue container with handle, selfie‑stick holder and a high‑quality hook knife – all elements geared to real‑world tandem workflows. Dedicated spreader options (Soft, Soft Trim and Hard Hybrid) and compatibility with popular tandem wings such as the BIBETA series underline the harness’s professional focus.
Who the BIPRO 4 Is For
The BIPRO 4 is ideal for tandem schools, commercial operators and experienced leisure pilots who value a clean cockpit, uncompromising safety systems and a harness that stays comfortable over years of use. Its “Daily Ease” concept translates directly into fewer compromises on the hill, less fatigue over the season and a better overall experience for both pilot and passenger.
