Motorcycle Helmets with Micrometric Fasteners
Micrometric fasteners (sometimes called microratchet fasteners) are probably the most popular way to fasten a modern crash helmet. They’re easy to tighten up and, importantly, very easy to unfasten. Just make sure you adjust the strap adjuster on yours from time to time to ensure it stays a nice and tight fit. For more detailed information about micrometric fasteners, read here.
