The Howard Leight Shooting Safety Combo Eye and Ear Kit is a great starter package for anyone new to shooting sports. The shooting glasses feature a clear polycarbonate lens suitable for both indoor and outdoor use, and an anti-fog lens coating for extended performance. Extra flex built into the temple and a non-slip, rubber nose bridge provide added comfort and a secure fit. The ultra lightweight shooting earmuff carries a Noise Reduction Rating (NRR) of 25 to protect your ears from harmful shooting noises. An adjustable headband and soft ear cushions create a comfortable custom fit. The patented Air Flow Control (AFC) technology allows for a slim earcup design that ensures your firearm stock has clearance while shooting. All Howard Leight protective eyewear and shooting earmuffs are compatible for use with each other.
