A rope access workhorse that’s as durable as it is comfortable. It is built with aluminium attachment points, aluminium side attachments, steel adjuster buckles, moulded gear loops, tool loops, and an integrated chest ascender that can be easily swapped out when desired.


The ATOM is one of the most comfortable harnesses ever developed, is the culmination of stripping harness design down to the basics and re-imagining a performance-enhancing tool for rescue and rope access. CMC has incorporated years of feedback from experts who spend long hours in a harness. In addition, the ATOM harness went through rigorous field-testing, resulting in a harness design that improves safety, comfort and workflow efficiency in all the ways you can’t see, but feel.


Every detail in the ATOM Access Harness has been thoughtfully designed for the rope access professional. From the structure and attachment points to buckles, gear and accessory loops and other features, the ATOM delivers maximum comfort, workflow efficiency and durability in a lightweight and low-profile harness system.
