With an integrated CROLL L ventral rope clamp, the ASTRO BOD FAST harness is designed for greater efficiency and comfort during rope ascents. The gated ventral attachment point allows optimal integration of equipment (such as rope clamp, or seat). The wide, semi-rigid waistbelt and leg loops provide excellent support. They are contoured and lined with breathable foam padding for comfort when suspended. The DOUBLEBACK self-locking buckles at the rear of the harness, between the waistbelt and the leg loops, allow for a shorter adjustment when the dorsal attachment point is used.

The harness also makes it easier to carry and organize work tools, with multiple gear loops and slots for attaching CARITOOL tool holders and TOOLBAG tool pouches. It has a fall indicator on the dorsal attachment point and is certified to North American and European standards. ASTRO BOD FAST (international version) features leg loops with FAST buckles.
