Petzl – ASTRO SIT

The Petzl ASTRO SIT is a high-performance seat harness designed for superior comfort, gear integration, and adaptability in rope access and technical work environments. Featuring a wide, semi-rigid waistbelt and leg loops, the harness offers excellent support during suspension. These components are contoured and lined with breathable foam padding, ensuring long-lasting comfort even in extended hang times.

Ideal for professionals who need to carry tools and accessories while working at height, the ASTRO SIT includes multiple pre-shaped equipment loops, along with dedicated slots for CARITOOL tool holders and TOOLBAG pouches, keeping your gear organised and easily accessible.

A key advantage of this harness is its gated ventral attachment point, which opens to allow optimal integration of essential equipment. This includes direct connection of PROGRESS lanyards, the TOP CROLL rope clamp for efficient rope ascents, or the PODIUM seat, allowing direct descender connection while maintaining mobility at the ventral point.

The ASTRO SIT also features FAST LT automatic buckles on the leg loops for quick, secure donning—even while wearing gloves—and DOUBLEBACK PLUS self-locking buckles on the waistbelt for fast, precise adjustments.

For increased versatility, the harness is fully compatible with the TOP CROLL S or L chest harness, easily converting it into a full-body fall arrest system when needed.
