CMC’s Chest Ascender EVO is an ergonomic, easy-to-use ascender that’s ideal for climbing ropes.

Made of a lightweight alloy, the Chest Ascender EVO is designed to accommodate ropes with 10mm to 13mm diameters. The improved external profile for the ascender’s opening lever enables more effective climbing, while the efficient hole shape in the opening layer makes it easy to use the ascender even when you’re wearing gloves. The improved lower hole design keeps the ascender parallel to you during use. The patented anti-inversion cam system can be unlocked with one downward movement and features three cutouts to prevent mud buildup and reduce the force needed to slide the ascender up the rope. Certified to EN 12841:2006-B and EN 567:2013, CMC’s Chest Ascender EVO is reliable, easy to use, and ideal for climbing ropes.
