PETZL ASTRO® SIT HARNESS

The PETZL ASTRO® SIT Rope Access Harness is designed for professionals performing rope access, maintenance, inspection, and rescue operations in vertical environments. Its ergonomic structure provides excellent comfort and mobility while maintaining the high safety standards required for industrial work at height.

The harness features a semi-rigid waistbelt and leg loops with breathable 3D foam padding, ensuring optimal load distribution during suspension. This construction helps reduce pressure points during prolonged work sessions and improves overall comfort for technicians operating in rope systems.

A key feature of the ASTRO SIT harness is its gated ventral attachment point, which allows optimal integration of equipment such as descenders, rope clamps, and positioning lanyards. The gated design makes installation of devices more efficient and improves system organization during rope access operations.

The harness also includes foldable lateral attachment points for positioning lanyards and a rear attachment point on the waistbelt for restraint systems. These attachment points allow flexible integration with different work positioning and rope access configurations.

For efficient equipment organization, the waistbelt features multiple gear loops and attachment slots compatible with accessories such as CARITOOL tool holders and TOOLBAG pouches, allowing technicians to carry tools and equipment safely while working at height.
