3M Peltor Ultimate Hearing Protection sport muffs are designed for safety without sacrificing comfort while shooting or hunting. Sport muffs are designed to reduce sound levels for reliable passive hearing protection while still remaining comfortable for extended wear. They have a fully adjustable headband and are ergonomically engineered to reduce pressure points. The open frame design helps reduce heat buildup and improve comfort when worn with hats or caps. Soft comfortable rings provide for a better seal around the ears.
