Radical 4 Plus Airbag Harness Combo
The SupAir Radical 4 Plus is one of the best value student harnesses on the market and a regular recommendation for FlyWithJordan students. SupAir is a French manufacturer with decades of experience building harnesses that balance safety, comfort, and value — and the Radical 4 Plus reflects that expertise. The modular airbag system is the standout feature. The airbag provides serious back protection during launches, landings, and the inevitable training-hill tumbles of the learning phase. When you want to reduce weight for a hike, you can remove the airbag module and use the harness without it. The included reserve container is a meaningful bonus — most harnesses require you to purchase the container separately. Having it included makes the Radical 4 Plus a more complete package for a student building their first kit. French build quality is excellent and SupAir's reputation for durability means this harness will serve you well through your entire learning phase and beyond.
