Supair Radical4 including Airbag Module
PRODUCT OVERVIEW
Supair RADICAL 4
Light and modular hike-and-fly harness
The RADICAL 4 is an ultralight split-leg harness for mountain flying and hike-and-fly. In its stripped configuration it stays extremely compact; fitted with the removable Airbag Module, it becomes a reversible system with back protection, reserve compartment and carrying volume.
Cloudbase perspective
This is a modular mountain harness rather than a conventional all-purpose reversible. The attraction is being able to fly it light when minimum bulk matters, then add the Airbag Module when you want protection, reserve integration and backpack functionality. Choose the configuration around the flying you actually do rather than weight alone.
