The ASTRO harness is designed for rope access workers operating in difficult-access environments. Its design is specifically adapted to the requirements of rope progression and rope ascents. The padded 3D foam and the semi-rigid construction of the waistbelt and leg loops provide enhanced comfort throughout all phases of work. Its openable ventral attachment point allows optimal installation of equipment required for progression. The integrated CROLL L rope clamp improves efficiency during rope ascents. The waistbelt, equipped with metal side attachment points, gear loops, and tool holder slots, enables users to organize and carry all the equipment needed for a full workday. Finally, donning and adjusting the harness is simple and practical, even when wearing gloves, thanks to the opening FAST buckles and self-locking DOUBLEBACK PLUS buckles. Available in 3 sizes
