Almost melt-proof! World famous in arborist circles for its ability to resist heat generated in quick descents.
The secret formula lies in the unique mottled cover blend of Technora and polyester over a core of lightweight Spectra 900. Donaghys Spectra core incorporates a world-first safety feature made up of twin Kevlar strands which, in the unlikely event of cover failure, prevent the core from being cut or melted completely.
Armor-Prus has a very low stretch and is easy to splice - making it perfect for prusik lines. Technora is rated 234°C higher than standard polyester. Approved for use (and popular in) International Tree Climbing Competitions.
