The MARK + SARA Complete Kit includes everything needed to integrate MSA Sordins to your helmet system.

The Modular Attached Rail Kit (MARK) allows the end user to seamlessly integrate their hearing protection and/or integrated communications into their headborne systems and improve the consistent seal of ear protection. The MARK is compatible with every major helmet type and the most popular electronic hearing protection. Constructed of impact-resistant polymer, the MARK is designed for use in the most austere environments.

Sordin Arc Rail Adapters (SARA) were derived out of a need to directly attach MSA Sordin’s directly to an end user’s helmet. Rather than reinventing the wheel, the SARA calls on the spring tension generated by the Unity MARK rail adapters (sold separately) to achieve proper seal around the users ears and seamlessly integrate into the user’s head borne system. Lightweight, streamlined and designed with the simplicity and strength demanded by the end user, the SARA eliminates the headaches and discomfort associated with wearing over the ear head-band ear pro inside the helmet.
