The Supersonic RS is designed with a special forehead for cooling. Designed with 2 air vents positioned to the outside of the helmet beneath the visor, the Supersonic RS will increase airflow over the forehead and temples. Our exclusive Bee Stop mesh and Double In-Mould process allows us to put such large ventilation openings at the front without worrying about insects smacking into rider's scalps. This was something mountain bikers, in particular, seemed to run into, so we molded in Bee Stop. We've also been told that it helps keep hair from sticking out of the helmet. The Supersonic RS also features IAS 2 and a monomatic closure, features that ensure the widest range of adjustment and a precise fit that can be fine-tuned, one-handed, on the fly.
The UVEX fitting and adjustability system. It uses their proprietary IAS ring (Internal Adaptive System), which is a rear mounted dial driven adjustable retention system. The system allows easy circumferential adjustments, and can accommodate a wide range of head sizes, and headgear thicknesses used for inclement weather conditions. Simply twirl the dial, and the system tightens or loosens around the head.
