Results recorded attenuation levels as high as 99.99 percent within the measured range, with peak attenuation 78 dB. For those wishing to conduct their own testing, a quality meter is needed. Please note-cell phones are not a reliable way to test.

The adjustable hook-and-loop closure provides a comfortable fit for most adults and older children. The liner extends around the full crown and down the ear. - COMFORTABLE FOR WORK, TRAVEL AND EVERYDAY WEAR: Whether you're in the office, on a plane, commuting, or simply going about your day, this cap is designed to fit naturally into your routine.
