The ASTRO harness is designed for rope access technicians. Its design is specific to progression and rope ascent. The 3D foam padding and semi-rigid waistbelt and leg loop construction provide comfort throughout the workday. The gated ventral attachment point allows the user to efficiently install the necessary equipment for progression. The integrated CROLL L rope clamp improves efficiency for rope ascent. The waistbelt features metal side attachment points, equipment loops, and tool holder slots, allowing the user to organize and carry all the necessary equipment for a day of work. The DOUBLEBACK self-locking buckles and FAST opening buckles make donning and adjusting the harness simple and convenient, even while wearing gloves. The harness also features widely spaced shoulder straps to reduce neck chafing and sliding straps for more freedom and ease of movement. The harness is available in black color and is suitable for both men and women.
