Petzl Astro Sit

Petzl Astro Sit

The Petzl ASTRO SIT sit harness is purpose-built for professionals working at height and rope access technicians seeking a lightweight, comfortable, and modular solution. Its streamlined design allows it to be upgraded into a full-body fall-arrest harness by connecting a TOP CROLL chest harness, ideal for rope ascents.

Featuring a semi-rigid construction with 3D foam padding on the waistbelt and leg loops, the ASTRO SIT delivers superior comfort whether walking or suspended during long workdays. The textile bridge enhances mobility at the workstation, while the gated ventral attachment point enables quick and secure integration of essential progression equipment.

The harness is equipped with multiple gear organization options, including foldable metal side attachment points, seven pre-shaped gear loops, tool holder slots, and compatibility with CARITOOL and TOOLBAG accessories. DOUBLEBACK self-locking buckles and FAST automatic leg loop buckles ensure fast, glove-friendly adjustments and secure fit.
