Pro Ears ReVO Passive Earmuffs are for smaller heads and ears. These NRR 26 muffs are designed from the ground up to fit smaller heads. Suitable for a moderate noise environment, at the range, hunting, rock concerts or racetrack, they have all the same features you expect from Pro Ears passive hearing protection, but they provide a better fit for children and smaller adults which means better hearing protection. Rugged construction, an adjustable headband and super-sized Proform leather ear cushions make them very comfortable. It has a tighter radius headband, and specially shaped ear pads to eliminate gaps in the seal around the ear near the jaw line on smaller heads. These earmuffs are made in the USA.
